Do you (directors and actors chime in here) feel it is snobby or rude to turn down a part because it's not the one you want or not as big as you'd want?

I do theater and wrestle professionally.  I don't mind taking time off of wrestling to do shows, but when I get parts I don't want or ensemble I both feel weird about turning them down, but also feel weird about telling my wrestling promoter I can't make X, Y and Z shows because of theater.  Than the promoter asks if I got a big part and I must honestly explain my 3 mins of on stage time.

Thoughts?

I guess what I should do is clear.  Have you been with casting committees that have said, "Oh here's a Primadonna/Diva that will only accept the lead..."

I just don't want to come across like that.  For me it's just about not being worth the time spent... and less about me being full of myself. 

Just be certain to take the time to familiarize yourself with the play before you decide which roles you'll accept.

I remember one "prima-donna" who would only accept the lead roles -- no matter if he was right for them or not.  When casting a production of "Harvey" the audition form specifically asked for which role would he like to perform.

Of course, he wrote in "Harvey."

The director was tempted to cast him without ever informing him the title character of the play is an imaginary rabbit and never appears onstage.  Much amusement was garnered at the idea of making this fellow sit backstage wearing a rabbit suit for hours on end.

Unfortunately, cooler heads prevailed and the actor was too embarrassed to admit his mistake.  He was certain to read the play before his next audition.
