Tobey Maguire, star of "Spider-Man 3," isn't sure he'd play the superhero a fourth time.

"I appreciate movies from a standpoint of entertainment and distraction, and I also love when people make movies that help raise awareness," says the 31-year-old actor, whose films also include "The Cider House Rules" and "Seabiscuit."

"I don't really have a lot of formed ideas. It's more just thoughts," he tells Men's Journal in its May issue, on newsstands Tuesday. "I might do another `Spider-Man' movie -- I don't know."

Maguire says "Spider-Man 3" has a "fresh story" for his character.

"The public is adoring him, and it goes to his head. He's behaving arrogantly and is self-involved, which changes the feeling of the character for me. And it just gets darker from there," he says.

Maguire says he talks to the media to publicize his movies -- "I don't feel compelled to share anything."

"I used to prepare to go to battle with journalists," he tells the magazine. "Now I don't have my feet planted. I won't talk about what I won't talk about, but I'm more relaxed about it."

Maguire says he began attending Alcoholics Anonymous meetings at 19 because his life had become oddly predictable.

"I have an addictive nature," he says, "an obsessive-compulsive nature -- well, I don't know that's what it is clinically. But I go to addictive extremes, and before I got sober, that became routine."

Maguire is engaged to Jennifer Meyer, a 29-year-old jewelry designer. They have a 5-month-old daughter, Ruby Sweetheart.

"When she smiles, it's the most fantastic thing ever," he says. "But it's not like I didn't expect that. I expected to fall completely in love with my child."

Columbia Pictures' "Spider-Man 3" opens May 4.
