Dear Ben Affleck—please don't bulk up for Batman too much.
At least not while you're still filming Gone Girl.
The upcoming caped crusader has been asked to refrain from working out too much while making the much-anticipated thriller.
"I'm trying to keep him at the size he's at right now until he's done with us," Gone Girl costume designer Trish Summerville told me at the Catching Fire premiere in L.A. "I'm sure he's working out but I think for him, he's probably a guy that builds up really quickly so I just kind of asked him if he can stay where he's at right now."
Rumors that he could have been hitting the gym pretty hard took off late last month after photographers snapped a seemingly muscled up Affleck while out for chores with his daughter Violet.
"He's a really big guy, like he's quite tall," Summerville said. "You don't realize how big he is. He kind of reads smaller on film than he does in real life."
And Summerville reiterated what we've known for a long time, "Ben couldn't be lovelier. He's so nice."
Gone Girl is an adaptation of writer Gillian Flynn's best-selling novel of the same name. Directed by David Fincher, the movie also stars Rosamund Pike, Tyler Perry and Neil Patrick Harris.
It's scheduled for release on Oct. 3, 2014.
"It's great to collaborate when people are so talented," Reese Witherspoon, who's producing Gone Girl, told E! News at last month's Elle Women in Hollywood gala. "I'm just thrilled that the movie is getting made so quickly…and this author Gillian Flynn, who is so talented, is having so much of her work produced now."
