Some of the Avengers are assembling to push for clean-energy legislation in California.
Mark Ruffalo, a.k.a. the Hulk, Chris Evans, a.k.a. Captain America, and Don Cheadle, a.k.a. War Machine, have been tweeting and calling lawmakers' offices to rally support for Senate Bill 100.
The legislation, which appears unlikely to advance before the session ends Friday evening, would phase out fossil fuels for generating electricity by 2045.
