Huh... looks like it's an actual movie. I just thought it was one of those "rumors".
New trailer and stuff at the official site:
Fantastic Four Movie
Looks pretty awesome, too. I wasn't a huge fan of the first movie (it was very basic, plotless, and rushed towards the end) but this sequel looks as if it could be awesome...
... especially if Galactus shows up.
The first movie wasn't offensive, so I'll definitely give this one a shot as the Silver Surfer is one of my favorite characters
