Sean Gunn has retired from performing the on-set motion capture for Rocket Raccoon in the Guardians of the Galaxy films because of the physical demands.

Gunn, who recently turned 50, said the crouched position and repeated pivoting strain his feet and ankles and `hurt after a while`.

Bradley Cooper voices Rocket, while Gunn provided the character`s on-set motion reference in all three Guardians of the Galaxy films, released in 2014, 2017 and 2023.

Gunn also plays Kraglin Obfonteri in the Marvel films, including Guardians of the Galaxy, Avengers: E ndgame and Guardians of the Galaxy Vol 3.
