So the market said yes to Time Warner's (NYSE: TWX) new movie starring Jim Carrey, Yes Man. I know, that's an awful pun, and I'd be willing to bet that other articles about this past weekend's box office results said something similar. Sometimes you just can't resist. But, yes, Yes Man ruled at domestic multiplexes and grossed about $18 million according to early estimates from Boxofficemojo.

Here's the thing, though -- is an $18 million opening that great for Jim Carrey? Furthermore, as of the early estimates, Sony's (NYSE: SNE) Seven Pounds, the number-two film, actually grossed only $2 million less than Yes Man, and to add further insult, its per-theater average was higher. Shouldn't Carrey's star power have guaranteed a wider margin of victory? For that matter, what's Will Smith, the star of Pounds, doing in second place?

It just goes to show institutional shareholders of media companies that big star salaries simply do not guarantee runaway hits on the silver screen (I keep hoping that they'll complain about celebrity compensation, but so far, there have been no takers whatsoever).

I had high hopes for News Corp.'s (NYSE: NWS) remake of one of my favorite sci-fi films from the 50s, The Day the Earth Stood Still. I'm not sure what everyone else was thinking, but I figured the film would take in at least $50 million at the opening weekend.

Unfortunately, according to early estimates at Boxofficemojo, Earth could only scare up around $31 million in its first three days at domestic theaters. In fact, compared to last year's I Am Legend from Time Warner (NYSE: TWX), which came out at about the same time, and was another remake of a famous cult sci-fi flick as well, it performed poorly as Legend, starring Will Smith, grossed $77 million in its debut weekend.

Keanu Reeves starred as the alien Klaatu in Earth. One has to wonder how the box-office dynamic would have changed if Will Smith was in the role. Of course, maybe the movie would have been more expensive to make (although I'm sure Reeves doesn't come cheap, either). I heard great word on the remake from a friend of mine who saw it over the weekend on an IMAX (NASDAQ: IMAX) screen and really enjoyed it. He was a bit surprised when I suggested that the film only pulled in around $30 million.

It's the Fourth of July weekend, and movie studios want to capture as much money for their films as possible, even if they've already been in the theaters for several weeks. No matter what, though, Sony (NYSE: SNE)'s Hancock, starring the always excellent Will Smith, is set to be the financial superhero of the weekend. Already, as of this writing, the film has taken in about $24 million through Wednesday, according to Boxofficemojo. The movie had some showings on Tuesday before its official debut in the middle of the week. It was number one on Wednesday, followed by Disney (NYSE: DIS)'s Wall-E. The robot flick so far has a total tally of around $86 million.

Poor Marvel (NYSE: MVL) and its The Incredible Hulk project. Will anybody be interested in seeing the big green guy now that Hancock is in the marketplace? Indeed, Hulk took in less than a million bucks on Wednesday, and it ranked number seven for that day. Looks like the Hulk fever is winding down at the multiplex, and it looks like Marvel's stock has had its run for the time being. The stock closed on Thursday at $31.20, well away from the 52-week high of $37.41. I still hold Marvel shares, and although there are no big catalysts on the immediate horizon, I have a long-term outlook on the company. Still, the trader in me wishes that I had lightened up on the position back at the $37 level to book some gains.

Hancock should do well north of $100 million once the Fourth of July holiday period has passed. The marketing, in my opinion, is very compelling, and from what I know about the story, it's a smart idea that provides a nice balance to the frivolous plots of Iron Man and Hulk (I'm using the term "frivolous" here with affection). Sony's scored a hit, maybe even a new franchise (I haven't seen the film, so I can't say if a sequel is feasible or not within the confines of the concept), but it won't do much to move the company's stock. Those looking to play the Hollywood game might want to wait for Marvel to pull back further from current levels.

Disclosure: I own Disney and Marvel; positions can change at any time.

The Walt Disney Company (NYSE: DIS) got a nice present today in the form of the nation's number one movie, National Treasure: Book of Secrets.

The sequel to the 2004 blockbuster, National Treasure, National Treasure: Book of Secrets had a monster weekend, with $45.5 million in sales. Nicolas Cage is once again the leading man in this movie, and in this thriller, Cage's character, Ben Gates, is in a struggle to clear the name of an ancestor that has been implicated in the murder of Abraham Lincoln's assassination.

If the first installment of this series is any indication, Disney could be seeing some pretty big numbers from this movie before it is all said and done. When National Treasure debuted in 2004 the movie raked in $35.1 million and ended up with a total of $173 million at the box office.

Score another big success for Will Smith. His latest blockbuster, I am Legend, grossed $76.5 million in its opening weekend -- the best December opening for a movie in history.

The record take also crushes Will Smith's second best opening by nearly 50%; I, Robot, a hit by any measure, debuted with revenue of "just" $52.1 million. Not only that, but it also ranks as the best December opening of all time, beating the $72.6 million start for Lord of the Rings: Return of the King in 2003, Warner Bros., the Time Warner Inc (NYSE: TWX)-owned studio said.

And all this from a man who isn't particularly talented; he said so himself. He recently explained his success to 60 Minutes this way:

I've never really viewed myself as particularly talented. I've viewed myself as slightly above average in talent. And where I excel is ridiculous, sickening, work ethic. You know, while the other guy's sleeping? I'm working. While the other guy's eatin'? I'm working. While the other guy's making love, I mean, I'm making love, too. But I'm working really hard at it.

There's some career/life advice to pass onto your kids. Success generally requires some talent, but that's not the major factor. Most successful people have gotten there through hard work. A good work ethic might be the most important talent of all.
