LOS ANGELES — Tobey Maguire says he and his big-screen alter-ego, Spider-Man, "have very different lives." Still, both are caught in the same web of uncertainty: What next?

Friday's release of "Spider-Man 3" raises as many questions as it answers for the web-slinging hero and the actor behind him.

Is the Spidey franchise finished? Will Maguire sign on for a fourth installment? Will Peter Parker propose to Mary Jane? How will fatherhood and marriage affect Maguire's future? What roles lie ahead after superhero success?

"Everything's in transition for me," says the actor. "My friendships, where I want to live."

And his work. After playing "Spider-Man" for six years, and fitting in "Seabiscuit" and "The Good German" in between, the 31-year-old star is looking at a wide-open calendar. His top priority is spending time with his fiancee, Jennifer Meyer, and their 5-month-old daughter, Ruby Sweetheart. But workwise?

"I don't have any specific ideas," he says, looking sharp in a gray suit, white shirt and Hollywood stubble, sitting in a suite at Beverly Hills' Four Seasons Hotel. "I want to work in all types of movies. I don't care the size of the movie. I want to work in different genres and different types of films. It just all depends on scripts and directors."

He's not ruling out another adventure with Spider-Man and its three-time director, Sam Raimi. But he's not ruling it in, either.

"If there's a script I love, if the character goes in directions that I think would be great, and if Sam's involved and the right cast is there, then I would consider it at that point," Maguire says, adding that it could take years to develop a script for "Spider-Man 4."

"I think they would love for Sam to do it, so we'll just see."

Maguire says he doesn't feel he owns the role.

"I don't go to bed at night thinking, 'Ah, I'm Spider-Man,' " he says. "These are properties for these studios and ... I won't be doing them forever, whether I do another one or not."

Meanwhile, he's enjoying the accomplishment of finishing a six-year project. He celebrated with some time off before jumping into the movie's marketing madness, which included a trip to Tokyo and a jaunt to New York City. He likes "being part of the event."
