William Shatnermay be best known for his role inStar Trek, but the veteran actor has never even seen an episode of the iconic show.

“I have never watchedStar Trek,” he said. “There are many episodes I don’t know, there are some movies I don’t know.”

He added that he did watch one of the franchise’s many movies,Star Trek V: The Final Frontier,but only because he directed it.

“I directed one of the movies — No. 5 — I had to watch that one,” he said. “But it’s all painful because I don’t like the way I look and what I do.”

Shatner previously told PEOPLE his chemistry with Smart, 69, was “the same as phosphorus and water. An intense fiery meeting that generates light and heat to an enormous degree and just as suddenly is extinguished because remember we are both a little older.”

Smart said the two had previously had “a lot of fun” on Shatner’s 2010 series$#*! My Dad Sayswhere they played warring neighbors who eventually fell in love.

“InSenior Momentwe play characters who are so different with such different lifestyles that it’s fun to see them negotiate a romance; as a friend of mine says: ‘They fill in each other’s gaps,'” she said.
