(I love Downey Jr, too, and D'Onofrio who's also in The Judge.)The Wedding Ringer--Kevin Hart and Josh Gad. Cute and funny in places. Regular comedy fare.
The Judge--with Robert Downey, Jr. and Robert Duvall. Thoroughly enjoyed it. I'm a big Downey fan though. Seriously, this guy is my age--looks like he's 20.
Titanic. Perhaps you've heard of this one. Features a huge ocean liner.
It sinks.
