As we learned last week from his hilariously honest Reddit AMA, no topic is too taboo for Channing Tatum to discuss. So when the “Magic Mike XXL” actor appeared on “The Howard Stern Show” on Tuesday (June 23), he wasn’t too shy to put one of his own movies on blast.

While discussing Tatum’s résumé, Stern mentioned the 2009 blockbuster “G.I. Joe: The Rise of Cobra” as a turning point in the actor’s career. But Tatum couldn’t stop laughing at that notion, finally admitting that he only signed on for it because of a contractual obligation to Paramount Pictures.

“I’ll be honest, I f--king hate that movie. I hate that movie,” Tatum said. “I was pushed into doing that movie. From ‘Coach Carter’ they signed me to a three-picture deal […] They give you the contract and they say, ‘Three-picture deal, here you go.’ And as a young — you’re like, ‘Oh my god, that sounds amazing. I’m doing that!’”

As he recalls, he started to build up his career over the next few years with films like “She’s the Man” and “Step Up.” Finally, Paramount called him to fulfill his contract with “G.I. Joe.” Tatum says he’d grown up watching the animated series and initially wanted to play Snake-Eyes, but the studio shot down that request.

“The script wasn’t any good… I watched it every morning, like, growing up,” he said. “and I didn’t want to do something that I thought was 1. bad, and 2. I just didn’t know if I wanted to be G.I. Joe.”

The film went on to gross $302 million worldwide, and its sequel — 2013’s “G.I. Joe: Retaliation” — made $375 million, so it quite literally paid off for Tatum in the end. Besides, he does admit that it could have been worse.

“I could have been given… I don’t know, ‘Scream 5,’” he quipped. “I’m super lucky and blessed to have been given that film. That was really not all that bad.”

Still, he does admit that life doesn’t necessarily change the way you want it to after playing the lead in such a successful box office smash.

“It does, but maybe not from the people you really want [to be] calling,” he said, adding that the esteemed directors Joel and Ethan Coen weren’t among the filmmakers hitting him up after that.

Tatum was only slightly less subtle during his AMA last week when he shared in the communal confusion surrounding another one of his somewhat disappointing blockbusters, “Jupiter Ascending.”

“‘Jupiter Ascending’ What was that?” a fan asked, to which Tatum replied, “Great question. I have the same one to myself.”

But remember, people… that movie DID give us Channing in a black leather bodysuit doing badass stunts. Just sayin’.
