Calm down, 2020!

Jackass stars Johnny Knoxville and Steve-O were hospitalized just a few days into the filming of Jackass 4.

According to costar Bam Margera, the actors were injured while "jumping on a full-speed treadmill" while holding a tuba.

Knoxville is currently 49 years old and Steve-O is 46. It's been ten years since the last Jackass movie, 2010's Jackass 3-D.
