It's looking likelier and likelier that Joseph Gordon-Levitt's days of stalking around Gotham City in a cape and cowl have ended before they ever really started. By the end of "The Dark Knight Rises," Gordon-Levitt's optimistic beat cop John Blake — real name Robin, as it turns out — discovered Bruce Wayne's abandoned Batcave, leaving him the heir apparent to Batman's legacy in Gotham.

Gordon-Levitt hasn't been shy about his beliefs that the ending of "Rises" wasn't meant to be a "to be continued," but a decisive conclusion to the "Dark Knight" trilogy and its themes. Given that Christopher Nolan has also said that he won't be involved in future Batman films, it's a safe bet that further appearances of JGL in Gotham aren't in the cards, either.

But how about that "Justice League" movie that Warner Bros. is currently assembling? It's unclear at the moment how WB plans to connect their superhero team-up (rumored to hit theaters in 2015, the same year as Marvel and Joss Whedon's "Avengers" sequel) to the "Dark Knight" trilogy, if at all. But for the sake of argument, let's say Gordon-Levitt was approached to be a part of "Justice League" — would he even be interested in signing on?

"It always depends," he told MTV News at the Toronto International Film Festival, where he was busy promoting "Looper," his upcoming sci-fi thriller from "Brick" director Rian Johnson. "I always pick projects that I want to be involved in for the same reasons. Is the script really good? Is the filmmaker a really inspired artist that I feel connected to? That's what I always pay attention to."

Based on that logic, perhaps Gordon-Levitt wouldn't be interested in just any director taking on "Justice League." But if the keys were handed to someone like, say, "Girl with the Dragon Tattoo" filmmaker David Fincher?

"Really?" Gordon-Levitt responded to our hypothetical with a laugh. "David Fincher?"

Hey, you never know — even Nolan seemed like an unlikely fit to direct the Caped Crusader before "Batman Begins" hit theaters. Now, though, not only is Nolan's vision of the comic book movie genre well-documented, it might also be positioned for some awards recognition at next year's Oscars.

"Sure," Gordon-Levitt said when asked if he's hopeful about "Rises'" chances at the Oscars, agreeing that that kind of attention is nothing but a good thing. "Yeah, exactly."
