Our amigo Kebe pointed this out: Roland Emmerich is apparently not the first person to try and beat Irwin Allen at his own game. Long ago, there was a disaster movie classic that Emmerich appears to be trying to remake. Seriously, it's almost a shot for shot deal except for now we have better FX and no Donald Sutherland.
The resemblance is downright eerie, don't you think? I'm not usually a fan of litigation, but if John Landis, Jim Abrahams and the Brothers Zucker decided to sue, I'd laugh my ass off.
