In an interview with MTV News, Hutcherson revealed that he was immediately taken with Peeta and that the role resonated with the type of person he is.
He said: "For me, Peeta is an amazing character. I fell in love with him right away. What's crazy is that I've never seen a character that's so much of who I am as a person.
"I just feel like his self-deprecating humour, his outlook on life, how he doesn't want things to change him - that's really part of who I am as a person.
The actor, who won the lead role in the on-screen version of Suzanne Collins's dystopian trilogy alongside Jennifer Lawrence and Liam Hemsworth, said that it was important to remain unaffected by fame.
"Being in this movie business from a young age, from nine years old, there's a lot of times where you could let things change you, let people have a big effect on you," Hemsworth added.
"You have to make sure you stay true to who you are and what your value system is, that was really important to me from a young age, and I think that's something that really attracted to me about Peeta, because that's how he is as well.
"He's very much like myself. He's outgoing, very much a people person, he has a way of being able to talk to anybody he meets."
The Hunger Games is directed by Gary Ross, and stars Jennifer Lawrence, Josh Hutcherson, Liam Hemsworth, Woody Harrelson, Lenny Kravitz, Donald Sutherland, Toby Jones and Stanley Tucci.
Based on Suzanne Collins's best-selling novel, the film is released in the US and UK tomorrow (March 23).
