Watching a random episode of Star Trek: The Next Generation on TV. I didn't realize that David Warner was in that show. I had to look it up, but even under all of that Kardassian (not sure if I spelled that right) make-up, I could still recognize his voice.
It likely helps that I'm mainly familiar with his voice between Batman the Animated Series and Doctor Who Big Finish stories. (I only recently found out that he was Sark, Dillinger, and the MCP in Tron)
Also, it feels weird to see Data wearing a red uniform.
