Well, G'Kar was in TNG and The Fugitive (Harrison Ford version). Sheridan and Londo were in Tron, I'm told, although I haven't seen that. Ivanova was in some alien-possessed stripper movie..... Lennier was in Lost in Space (not the Hurt movie) I saw Sheridan in an Outer Limits episode once. Lyta was a stunt double for Doctor Crusher and Major Kira. Really not a lot out there, come to think of it.
