You'd think Starfleet wouldn't enlist somebody who was "howling mad," and yet that's exactly who actor Dwight Schultz was most famous for playing before he joined the cast of "Star Trek: The Next Generation." Trekkies know Schultz as Lt. Reginald Barclay, the Enterprise's nervous engineer, but fans of '80s action might better recognize him as H.M. "Howling Mad" Murdock from "The A-Team."

In the mid-2000s, Bryan Cranston played Lucifer in ABC Family's Fallen miniseries, an adaptation of Thomas E. Sniegoski's The Fallen books.

Ensign Pavel Chekov served aboard the Starship Enterprise for most of "Star Trek: The Original Series."

It wasn't until months after the premiere that he met the voice of the talking automobile, William Daniels.

It's not always a given that writers will approve of TV or film adaptations of their books. Sometimes, authors hate their adaptations. Legendary sci-fi author, Isaac Asimov, died decades before Apple TV+ turned his acclaimed "Foundation" novels into a show. While we might never know what he would've thought, his daughter approves — and thinks he would have, too.

There were some major character deaths in the "House of the Dragon" Season 3 finale — which shouldn't comes as a shock considering people die in Westeros all the time. Still, some viewers might have been surprised that Aemond survived his encounter with Aegon, even though the deposed king arrived at Harrenhal seeking revenge after being horrifically burned by his brother last season.
