Mark Ruffalo signs up for six more Marvel films?

London: Hollywood actor Mark Ruffalo has reportedly signed up for six more Marvel films and he says starring in `Avengers Assemble` has given him more appetite to appear in the forthcoming comic book projects. The 44-year-old, who plays The Hulk/Bruce Banner in the comic book company`s latest movie, had a great time working on the star-studded motion picture, reported Contactmusic. "The experience was great, I really had a great time, it was fun. When we got the script I thought it was great and then we kept getting re-writes and each one just got infinitely better. "It`s getting tighter and better, but it`s nothing compared to seeing the movie for the first time. I was so impressed and blown away at how much he packs into this movie and how exciting it is and what a great ride it is," Ruffalo said. The actor said he was impressed with how much director Joss Whedon managed to fit into the two-hour 20 minute motion picture. PTI
