Actor Robert Downey Jr. posted on his Twitter a time and date of a virtual rally for followers to join to raise awareness about voter registration and voting. He also posted proof that he and MCU science-bro, Mark Ruffalo, voted already in the 2020 presidential election.

Actor Tessa Thompson not only asked her followers to vote but also promised that if they texted 30 of their friends -- to remind them to vote, specifically -- that they'd receive a personal thank you from the star.

The actor also posted that after voting by mail, it is as important to track the status of the ballot to ensure it's delivered and counted in your district. She likened checking a voting ballot to ordering a pizza and jokingly said that a voter could do both in the same amount of time.

Although both Evans and Downey Jr. are currently not slated to appear in another MCU film -- though there are rumors that Downey Jr. will cameo in Black Widow -- at the moment, Thompson is next set to star in the MCU film, Thor: Love and Thunder.

Directed by Taika Waititi, Thor: Love and Thunder stars Chris Hemsworth as Thor, Tessa Thompson as Valkyrie and Natalie Portman as Jane Foster. The film is set to arrive in theaters on Feb. 11, 2022, pending any delays from the coronavirus (COVID-19) pandemic.
