Actor Mark Ruffalo, who will reprise his role as Bruce Banner aka Hulk in the superhero film “Avengers: Age of Ultron”, is not sure whether Hulk will get a solo film in near future.

The 47-year-old teased fans about what will possibly happen to his character and his teammates in the much awaited film in an interview with Empire magazine, reports aceshowbiz.com.

“Who knows where these things will go. But as Bruce is able to impress his will on the Hulk -- going into The Hulk and being inside the Hulk when he's raging - The Hulk's will is also growing and able to impress upon Bruce... It'll be interesting to see if that ends up being what would be the next Hulk movie,” he said.

“(A new feature-length Hulk movie is) a tough nut to crack. Traditionally you're watching a guy who doesn't want to do the very thing that you want him to do. It's hard to take for two hours. I don't know how many times you can use that same framing for it, but now he's maturing and there's a cool dynamic growing between Banner and The Hulk,” he added.

“Avengers: Age of Ultron”, which also stars Robert Downey, Jr., Chris Hemsworth, Chris Evans and Scarlett Johansson, is set to release May 1.
