Meg Ryan and Dennis Quaid's son Jack is set to play one of the Career Tributes, according to Entertainment Weekly. This will be Jack's acting debut and he's set to star as Marvel, the mean male tribute from District 1.
It didn't say district 11 it said district 1, and district 1's tributes are glimmer and MARVEL.
Katniss finds out his name in Catching Fire when she visits District 1 on the Victory Tour, I believe.
I didn't know the book even revealed the tribute from District 1's name. He's the one who Katniss shoots threw the neck when he traps Rue, I don't recall them ever saying his name. Well I guess it's Marvel! lol
