When faced with a decision to either fight Thanos or sing along to an 'Endgame'-themed 'We Didn't Start the Fire' song for the whole world to see - which would you choose?

If you chose Thanos, then congratulations you're going to be just fine. Unfortunately for the cast of 'Avengers: Endgame', the same fate can't be said for them.

Late-night chat show host Jimmy Fallon has gone all 'Endgame'-mad this week, and ended up roping in the cast to sing along to Billy Joel's 'We Didn't Start the Fire'. Of course, the lyrics have been changed to include throwbacks to all 20 of the past Marvel titles, as well as appearances from all those who survived Thanos' snap.

Just look at the cast, including Robert Downey Jr., and Brie Larson, try to put on a brave face while they sing along below.

 

We're sorry Jimmy Fallon and the cast of 'Avengers: Endgame', but there's only one person who can screw up 'We Didn't Start the Fire' by Billy Joel and make us love the song even more. That's right, it's Leslie Knope, singing "daddy ate a squirrel."

 

Just in case you've forgotten, 'Avengers: Endgame' will release in Irish cinemas this Thursday April 25th. You can catch our review of one of the decade's most anticipated movie tonight, which will go live at 10pm.
