Kind of sort of.
At one of the Star Trek conventions I was at in the Thistle hotel back in the 90s, there was a video crew wandering about filming stuff. I didn't give them a second thought at the time, I was too bust enjoying myself and trying to get laid.
However, a couple of months later, I was over at a mates place, and we were surfing the foreign language channels on SKY in search of some porn.
On one channel, I caught sight of what looked like the weird water sculpture thing that the Thistle had in its foyer at the time (how it got broken, and who did the deed is another story for another time...). Sure enough, there was actress Nichelle Nichols (Lt. Uhura) being interviewed in German.
There then followed a montage of shots of general convention atmosphere - folks in Star Trek related costumes and so on. Then a shot of the dealers room, and in the middle distance, walking away from camera, was your humble obedient.
