Jared Leto hopes "Suicide Squad" is only the beginning of his portrayal of the Joker.

"I hope it's an introduction ... and not the end!" the actor tells the Toronto Sun. "Because I could easily just play the Joker a couple more times and then retire. Because it's so fulfilling and so creative and it's so imaginative. It's really difficult to think about doing anything else!"

However, Leto doesn't want to see his Clown Prince of Crime confined to the "Suicide Squad" franchise -- he envisions him going toe to toe against the Dark Knight in Ben Affleck's solo film.

"I think it would be incredible to see Batman and the Joker go head-to-head!" he says. "This Batman and this Joker. I mean, I don't know, that might be too much! But that would be fun."

Leto, whose method approach to "Suicide Squad" is already infamous, has called the Joker "a role of a lifetime."

Written and directed by David Ayer, "Suicide Squad" opens Friday nationwide.
