Long before Jason Momoa was confirmed to play Aquaman, the actor was initially attached to play Drax the Destroyer in Marvel's Guardians of the Galaxy, a role that eventually went to Dave Bautista. It seems that Jason Momoa may still harbor some ill will towards Marvel, as evidenced in a poster the actor signed for fan Liz Guadiana at the Indiana Comic-Con last weekend. When the fan approached Jason Momoa, she asked him him to sign her poster with a reason fans should join the DC Universe. His response was "F--k Marvel" which he wrote on her poster. Here's what Liz Guadiana had to say below.

"Hey guys, remember that poster I got? I had it signed at Indy Comic today by Jason Mamoa. I asked Jason, 'Can you write down a reason why all these DC haters out there should join our DC universe.' His answer on the left picture, 'F--k Marvel' LOL"

Of course, it's likely the actor was just joking, but this isn't the first time he's made an off-color remark. After his character Khal Drogo was killed off in the first season of HBO's Game of Thrones, he made the following statement, in regards to author George R.R. Martin.

"After George R.R. Martin killed me, I was like 'go f--k yourself.' I'm joking. But after George killed me, I was really upset. I went to go get the book at Barnes and Noble and I was bummed that I was dead. But it's brilliant writing."

Take a look at Liz Guadiana's poster signed by Jason Momoa below. Do you think the actor was just making a joke? Or do you think he is still upset about losing the Guardians of the Galaxy role? Let us know what you think below.
