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.

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.
