"The Divergent Series: Insurgent" ends on such a cliffhanger, even the stars of the film can't wait to see what happens next.

At South by Southwest Film Festival in support of "Insurgent," star Miles Teller told MTV News that he's totally ready to see what happens with his character and the wider world in the third movie, the first part of the two-part "Divergent" finale, "Allegiant."

"You hope that they come back for the second one and you hope that you get an opportunity to tell the entire story," Teller said of the series.

"The way the second one leaves you -- I ignorantly have not read 'Allegiant' so I'm excited to see what happens next," he said. "And it's very easy to find out, but I don't like to know those things. But at the end of the second one I was like sweet, I want to know what happens next. So I'll see when I read the script."

We've read the book, so we know what's up in post-apocalyptic Chicago, but for Teller's sake, we'll keep mum for now.

Check out more from Teller, including how he feels about "Insurgent" star Shailene Woodley repeatedly beating him up, in the interview below.
