At 93 years old, William Shatner has no plans to retire. In fact, he would love to reprise one of the roles he’s most known for. As part of the promotional process for his new autobiographical documentary titled You Can Call Me Bill, Shatner said that he would love to play Captain Kirk again in a Star Trek project, 30 years after last playing the part. Shatner is perhaps best known for playing Captain Kirk in the original Star Trek series and reprising the role in several spin-offs.
