Marvel Cinematic Universe (MCU) stars Robert Downey Jr, Mark Ruffalo and Zoe Saldana have rallied in support of co-star Chris Pratt who was dubbed "the worst Chris" on Twitter. A user started a poll on a website, asking people to choose the "worst Chris" from all the Chrises of Hollywood.

Defending his co-star, Downey Jr asked Pratt's detractors to look at their own lives before commenting on him. "What a world. The 'sinless' are casting stones at my brother, Chris Pratt. A real Christian who lives by principle has never demonstrated anything but positivity and gratitude." Downey Jr wrote in a post on Instagram alongside a photo of his with Pratt.

"If you take issue with Chris, I've got a novel idea. Delete your social media accounts, sit with your own defects of character, work on them, then celebrate your humanness. @prattprattpratt I #gotyerbackbackback (sic)," Downey Jr added.

Ruffalo urged Pratt's critics to leave him alone and refocus on the presidential election due on November 3. "You all, @prattprattpratt is as solid a man there is. I know him personally, and instead of casting aspersions, look at how he lives his life. This is a distraction. Let's keep our eyes on the prize, friend," he wrote.
