BTW, I know that, considering the high volume of new guest characters on every episode, recycling actors is inevitable. Still, I wish they wouldn't recast old Homicide regulars in new roles, since the shows are supposed to be set in the same universe.
On the other hand, a number of L&O lead characters have been played by actors who'd earlier appeared in different roles, such as Jeremy Sisto, who played a defense attorney before being cast as one of the cops. So they've recast actors within the same franchise. Which is bound to happen with any long-running series (just look at Star Trek
and its frequent uses of Vaughn Armstrong, Suzie Plakson, Jeffrey Combs, and others).
