The Last Song star, who is currently dating Miley Cyrus, revealed that he has already been ambushed by female fans hoping to become Mrs Liam Hemsworth.
"We've been travelling around and doing premieres all over the world so, so it's been a little crazy over the last couple of weeks," the actor told Access Hollywood.
"There's been a lot - I've been asked to marry a few people, which has been interesting - people I don't even know, so that's been fun."
While co-star Josh Hutcherson had to pack on a few pounds for the film, 22-year-old Hemsworth explained that he had to lose weight for the role.
"My character lives in District 12, which is kind of the poorest district, and he's not eating a lot," he said. "So I lost quite a bit of weight for the role."
The actor had originally hoped to to play Gale in the film.
The film also stars Woody Harrelson, Lenny Kravitz, Elizabeth Banks and Stanley Tucci.
The Hunger Games is released in the US and UK tomorrow (March 23).
