Chris Barrie was in The Brittas Empire while Red Dwarf was in its heyday. Isn’t this just what actors do though - play different characters?

^But not that often on two different shows at the same time.

Kristen Kruek was on some Canadian high school show at the same time she was playing Lana on Smallville. The actress who played Tigress on Stargirl was also the voice of the youngest daughter on Duncanville. At one point, both shows were on at the same time!

David Jason was in both Open All Hours and Only Fools and Horses, which overlapped each other by several years.

Christopher Meloni on both Oz and Law And Order SVU.

This is the one I thought of first.

It’s tougher to figure out now with streaming. For example, Adam Scott is in Severance, Loot, and doing voice work, but I think they’re all being made at different times which, to me, runs against the interesting part of the question. I think they should have to be in production at the same time, otherwise it’s like, no big deal.

Richard Deacon playing Mel Cooley on the Dick Van Dyke show and Fred Rutherford on Leave it to Beaver. Of course, it's not like they were really very different characters.

Mabel Albertson played Darren's mother on Bewitched and Howard Sprague's mother on The Andy Griffith Show.

David Jason was in both Open All Hours and Only Fools and Horses, which overlapped each other by several years.

Only Fools And Horses also overlapped with The Darling Buds Of May, which started in 1991. The man’s commuting skills must be absolutely god tier.

Lisa Nicole Carson was one of the leads on Ally McBeal and had a recurring role (29 episodes) on ER at the same time.
