I was always surprised they didn't have Selar cameo in Nemesis to get all the main cast TNG actors in there. She could easily have been one of the Romulans killed at the start.
Please tell me you meant Sela and not Selar! I don't want Dr. Selar to turn out to be a Romulan or to get killed!
It's the twist no one would have seen coming! Or my cock up.
Agreed on an O'Brien cameo somewhere would have been nice. Having a whisky at Riker's wedding would have been cool.
