Mark Ruffalo is the 67-year-old Hulk 

This past spring, ten years ago, Mark Ruffalo made his cinematic debut as Bruce Banner, 

the new Bruce Banner of the Marvel Cinematic Universe, in Marvel Studios' Avengers: Age of Ultron.

In the ten years that have passed, half of the original six members of the team have 

left the MCU in one way or another, but Ruffalo has remained.

He is currently one of the longest-running actors in a rapidly evolving mega franchise, 

alongside Samuel L. Jackson's Nick Fury. Jon Favreau's Happy Hogan, 

Chris Hemsworth's Thor, and Jeremy Renner's Hawkeye. 

He has no plans to retire any time soon.

From a cameo at the conclusion of Shang-Chi and the Legend of the Ten Rings 

to his current significant Disney+ appearance, Endgame.
