Jon Hamm reveals Jeremy Renner broke his arms while 'Tag' shooting

Jon Hamm has revealed his "Tag" co-star Jeremy Renner broke both of his hands while shooting for the film.

Hamm joked that Renner, known for doing death-defying stunts as Hawkeye in Marvel's "Avengers" franchise, fractured his "firewood"-like arms on the third day of filming the new comedy movie.

"Jeremy Renner... Broke both of his arms on the same time. Day three of production. We had 40 more days to go.

"Keep in mind this is a man who's done a hundred 'Avengers' movies and been fine. And he does a movie about playing tag... both arms, like firewood, just snapped like a matchstick," the "Mad Man" alum told Ellen DeGeneres on her show.

Hamm said Renner then continued shooting for the film wearing "green casts".

"We eventually painted (them) out in the edit (as part of CGI)... He is a hardworking man," he added.

"Tag" is based on a story written in the Wall Street Journal back in 2013 that revolves around a group of ex-classmates who meet up and organise a game of tag that finds them travelling across the country.

It also stars Ed Helms, Isla Fisher, Hannibal Buress, Jake Johnson and Leslie Bibb.
