Spider-Man 4 News & New Promo Pic

USA Today talked with Spider-Man 3 star Tobey Maguire and producers Laura Ziskin and Avi Arad about the possibility of Spider-Man 4.

“We've done an amazing job at keeping things fresh," Maguire tells USA TODAY. But, he adds, "it's hard to imagine continuously coming up with stories that deserve to be told. I'm not sure if there are more stories for this character that are interesting enough to be excited about doing more."

Ziskin says they also thought of the Spider-Man movies as a trilogy but are open to more ideas. "We don't have a book we're adapting, like a Lord of the Rings," says Spider-Man producer Laura Ziskin. "It's open-ended. But this could be the last. We've never started on the next movie while we were working on the current one."

Some Spidey 3 footage will be shown at Comic-Con. "This is a going-home kind of thing," producer Avi Arad says. "We brought the first one here and the fans have supported us and (director) Sam Raimi from the start. We wanted to say thank you."

And Ziskin promises one foe will be Spidey himself.

"He'll have to battle villains within," she says. "I love what we've done with this character."

So does Maguire.

"This one, to me, has more interesting twists and turns" than the first two, e says. "It's been a fun ride."

Meanwhile, a new promo image has been unveiled.
