Just like his wife Mariette Hartley, actor Jerry Sroka has had a guest spot on Star Trek, in this case a role on Star Trek: Voyager.
Playing Laxeth the Talaxian in Star Trek: Voyager: Investigations gave Sroka a bit of a glimpse of how he might look in the future, at least according to his kids. “You looked just like Grandma!” they told him, after watching the episode.
