So that's 6 actors reprising roles which isn't bad going (Chekov, Tuvok, Kim, Zimmerman, Icheb and Adm Paris).
For the fact fans, in OGAM you brought back Chekov, Tuvok, Uhura, Harriman, Rand, Stonn, T'Pring (7) all played by their original actors, plus original actors playing new characters and a couple of recasts.
Renegades is a lot less of a nostalgia fest.
