I will not give away any bits of the film. There are two prerequisite films you should really enjoy before deciding to see this movie. If you enjoyed Castaway, if you enjoyed Aliens, you are going to like I Am Legend. If you didn’t like one of these or neither of these, don’t see Legend.
I was happily surprised to see the 5-minute trailer to the new Batman film, The Dark Knight, before the IMAX version of Legend. That too looks awesome!
In an early scene of Legend we see the billboard of a joint Superman and Batman film in one of the Time Square marquise. Are we seeing a signal from Warner Brothers?
If you are interested in seeing the 70’s version of Legend, rent Omega Man starring Charlton Heston based on the same novella. The Smith version is much more intense and interesting.
