John Ritter played totally against type in "Monogamy," the eleventh episode of "Law & Order: SVU" Season 3. Per Business Insider, the sitcom star's character was a doctor and the main suspect in a devastating case involving the murder of his wife, and removal of her unborn child from the womb. Ritter is just one of many A-listers who have guested on the hit show over the years. You probably forgot John Stamos starred in an episode of "Law & Order: SVU," for instance.
Funnily enough, the year after Ritter appeared on the show, his actor son Jason Ritter also popped up in "SVU." Jason told Closer Weekly he keeps his father close by watching his old work. "Sometimes I will turn on the TV and catch an old episode of 'Three's Company.' I always watch it. Occasionally, there is even an episode I haven't seen before. It's special to be able to do that," he explained.
The elder Ritter had an extensive TV career, featuring in everything from "Felicity" to "Touched by an Angel," "Buffy the Vampire Slayer," and "Tucker." Although losing his dad was incredibly difficult, it spurred Jason on to follow in his footsteps. As the actor told the Huffington Post, being cast on "Joan of Arcadia" around the time he passed helped Jason channel his grief into his work.
