Sometimes actors want to have a say in the words they're given; sometimes they want to stretch their artistic muscles; sometimes they look at the scripts they have to do and think, "I could do better than this!" When this happens, and the producers are on their side (or the network is), you have something written by a cast member.
Much less prevalent than Directed by Cast Member, particularly in these days of arc-driven television. Writing is less glamorous than directing, for one thing, and it's harder to develop a story from scratch than to bring someone else's to the screen.
Key to both of these tropes is that the actor gets into writing or directing through the show they're on, without having a previous background in it (let alone being the series creator).
As the examples show, sometimes non-dramatic Expanded Universe works can be written or co-written by actors, for name-recognition value. Often these works focus on the character the actor plays in the show.
For the opposite direction of crossover, see Descended Creator and Creator Cameo. For shows where the cast and the writing staff heavily overlap, see Cast Full of Writers.
Examples:
- Kaori Yamagata—under the pen name Sakurako Akino—voiced Queen Pumpkin in The Movie for Go! Princess Pretty Cure and was also the writer for one of the movie’s three acts. She later wrote the novel sequel to the movie under the same pseudonym.
- Similar to Directed by Cast Member, many English dub voice actors also tend to write the scripts for the dubs they're in. John Burgmeier (who is often the head writer for many Funimation dubs), Jamie Marchi, Emily Neves, Kristen McGuire, Monica Rial, Aaron Dismuke, J. Michael Tatum, Patrick Seitz and Caitlin Glass, just to name a few have written for several of the shows they star in.

- An unusual example exists in the case of Doctor Who Meets Scratchman, which was written by co-stars Tom Baker and Ian Marter but was ultimately never picked up for production. Had it actually been produced and released, it would've been an eclectic, Terry Gilliam-esque game of cat-and-mouse through time and space between the Doctor & company and Satan (named "Scratchman" for whatever reason) that would've culminated in a final battle on a giant pinball table. The script was finally realized as a novel by Baker (alongside James Goss — Marter having sadly passed away in the '90s) in 2019.

Marter also wrote an entirely original novel featuring Harry as the protagonist, Harry Sullivan's War. Marter and Tom Baker co-wrote a speculative script for a Doctor Who movie during their time together on the show, called Doctor Who Meets Scratchman, which eventually ended up as a novel called simply Scratchman — as Marter had died in the meantime the novelisation was a collaboration between Baker and Whoniverse writer James Goss.

His first sketches were the Colambo sketches, in which he played the titular character, and the success of those bits allowed him to join the writing staff full-time in addition to puppeteering. By the end of his tenure, he was the show's head writer.
- While not a specific sketch, Carroll Spinney (Big Bird and Oscar the Grouch) gave the idea to have real kids appear in unscripted bits with the Muppets. He also wrote the plot outline for the special Big Bird in China.

- Unlike Directed by Cast Member, very few episodes of the Star Trek franchise qualify - in fact, the only ones are DS9's "The Muse" (co-written by Majel Barrett-Roddenberry) and Voyager's "Life Line" (co-written by Robert Picardo). Both focused on those actors' characters. (Walter Koenig wrote "The Infinite Vulcan" for the animated series, but due to budget limitations, wasn't a cast member on that show.)
- Barry Watson wrote an episode of 7th Heaven (not one of the two he directed).
- Robert Culp loved doing this on his shows: Trackdown, I Spy, and The Greatest American Hero all had episodes he wrote (and directed).

Melina Kanakaredes wrote "Grounds for Deception" where Stella goes to Greece chasing a suspect - an ep which unfortunately drew mixed reviews from fans. Finally, Carmine Giovinazzo wrote "Sanguine Love," about the murder of a member of a vampire-like cult. This one was much better received by viewers.

- Jerry O'Connell and John Rhys-Davies each received a story credit on Sliders - O'Connell got a few such credits (such as on "Way Out West") while Rhys-Davies only got it for "The Exodus, Part 1." In the latter case, it was the culmination of his feud with the producers and network: they purchased an outline he pitched as an example of how the show could better use its potential, drastically rewrote it into the kind of embarrassing B-movie he'd been complaining about, and since he had just been fired for his outspokenness, reduced his character to a mumbling brain-damaged state, fatally shot him in the heart, and left his corpse behind on a radioactive planet... which immediately exploded.

- The Wiz had two of the leads of the 2015 NBC production, Elijah Kelley (the Scarecrow) and Ne-Yo (the Tin Man), help write a new song, "We Got It". In it, Dorothy and her friends proclaim that The Power of Friendship can help them defeat Evilene and get their desires granted.

- In 1955, The Archers had an episode where Grace Archer, the wife of Phil, was killed off. (It may or may not have been a coincidence that the episode went out on BBC radio the very night commercial television began.) The script had Grace's fate be conveyed in the final line of dialogue thus: "She... she died in my arms... on the way to hospital," but Norman Painting, who played Phil, suggested the line go "In my arms... on the way to hospital... she's dead!" Suffice to say that not only was this one of the most talked-about episodes of the soap, but Painting went on to write many, many episodes (and the book Forever Ambridge - 25 Years of The Archers), as well as act in them.
