This one will certainly go under the “WTF?” category of the day. At a press conference in Tokyo, actor Will Smith inadvertently revealed some of the plot of I Am Legend to the Japanese press. At one point, he even had film co-producer and co-screenwriter Akiva Goldsman shouting “Don’t give away the ending.”

This is coming to us from Reuters/Yahoo out of Tokyo. After Smith gave away the film’s ending, Goldsman pretended to be surprised, but ended up hanging his head in shame. At the end of the press conference, reps from the studio asked all present if they could keep the information secret, as leaking it would certainly spoil things for viewers.

From where I am sitting, this is one of two things: either it is a huge screwup by an A-list Hollywood star or it is a ploy to gain publicity for the film. No details were released as to what Smith said (not like we would want to publish them anyway), but there is no telling yet as to whether the ending he gave was the correct one. Time will tell. Either way, Big Willy Style has some explaining to do. I Am Legend releases in both the United States and Japan on December 14.

Up for Discussion: Do you think this is Will Smith slipping up or a shameless attempt to promote the film?
