I stumped some friends and classmates recently with this. Doubt it will take long for people here to figure it out, but here it is:
{{NOTEBOARD ME YOUR ANSWERS--DO NOT POST THEM HERE. I will post scores for those who send me their answers on the Noteboard}}
Points awarded for identifying each costar and the movies they were in given as clues, the stuff that is bold faced, AS WELL AS naming the mystery person (10pts for that!). 30 points available. Good Luck and enjoy!

Who am I?(10pts)
1) I played a character named Gaius.(1pt)

2) I played a character married to a Gaius.(1pt)

3) In one of the largest and most successful productions I've been involved in I costarred with a fellow who wore little boots; he had a bad case of chest pain in another film.(3pts)

4) In that same production, I costarred with a man who went down with his ship in one movie, and died beneath his steed in another film, one in which he costarred with another actor from our large production (4pts).

5) One of the costars of that production was also featured with me in a movie directed by the person who directed #3's second Oscar nominated performance. MJ probably loved this movie.(4pts)

6) Another costar from that large production played a Prince, a Boss and an Emperor. In the film he played the Prince he costarred with an actor who really believed in tradition and dreamed of being rich.(7pts)
