Although Bradley Cooper got credit for voicing Rocket, the physical performance of this iconic character merits particular focus. The difficult chore of supplying Rocket's on-set physical reference for motions fell to effects actor Sean Gunn. This meant he had to keep an uncomfortable crouched posture for long stretches of time throughout production to guarantee the other performers had the right eyeline and could connect properly with Rocket's role. Though sometimes disregarded, the physical demands of this position are absolutely vital for producing realistic interactions between the CGI figure and the human performers. Examining how Cooper's voice acting and Gunn's physical performance combined to produce one of the most iconic Marvel Cinematic Universe characters is intriguing. The painstaking attention to detail needed in contemporary special effects-heavy films is shown by the will to keep correct scale and positioning throughout filming.
