Drew Brees and his wife saw the "Noah" movie the other day ... IN COSTUME ... two by two.
The New Orleans Saints QB and his wife went to a screening of the new Russell Crowe flick by their home in San Diego ... wearing full bible regalia.
Brees -- known as one of the religious guys in the league -- even had a tin foil ax for good measure.
After the movie, Brees tweeted about the experience ... saying, "Saw @NoahMovie the other night at Cinepolis. Opens 3/28. Very intense! #thefloodiscoming."
We get the hashtag is for the movie, but weird since he's so strongly connected to the rebuilding of N.O. after the Katrina floods.
Still, looks like he had fun!
