McGillion expressed great interest in auditioning for the role of Montgomery Scott in the 2009 eleventh Star Trek film. “I grew up watching Star Trek and Scotty was my favourite character. It would be a great honour to follow in James Doohan’s footsteps," McGillion said. He had the endorsement of Chris Doohan, the son of original Scotty actor James Doohan, to play the role of Scotty in the film. Though the part ultimately went to Simon Pegg, McGillion still appeared in the film in a different role.
