John Larroquette was in Star Trek III ?
 

Wow, I learn something new every day.

I couldn't believe it when I read it.

He was the Klingon that asked Kirk, "Kill me, I do not deserve to live."

Never saw his face thru the make up or recognized his voice.

Now Christopher Lloyd was easy to spot because he looks like a Klingon even without the make up.

Run Marty!!

Loved "Night Court"!

only thing good he did was Night Court -

he was also pretty good as Kim Basinger's crazy ex boyfriend in 'Blind Date' with Bruce Willis

Didn't the guy from Frasier play a Klingon in one of the films too?

EDIT - no, I looked it up, he played a human.

And this ...
