I *think* that one of the shots of the dog running towards camera with the chopper in the background was from the original.
Just watched it and what a dull film. I don't tend to be a CGI basher and think that the effects in the original look a bit dated now, but much of the CGI in this is really bad. Mary Elizabeth Winstead, though too young for the role, makes a credible heroine and she is the only reason this is even remotely watchable. As this is so close to the original and yet far inferior, it's pretty much a pointless exercise.
