This Means War (2012 McG)

Buddy secret agents Chris Pine and Tom Hardy fight over Reece Witherspoon. That's it. It isn't very good, really, but amiable enough.

Controversially, Reece's character cites Notorious, Rebecca, Vertigo and anything 'from 1960 to 1972' as prime Hitchcock.

DVD includes three different endings which were filmed... which I think is quite telling.

There's a clip of Titanic in the background which means Russell Carpenter is shooting his own film.
