text: what to do at an open casting audition!? next thursday i am going to an open casting audition for the part of lyra in the golden compass, the first movie in the his dark materials trilogy. i have never been to an open audition for a movie before i was wondering if anyone had any advice! yeah what iamhitchcock said. they'll probably just look @ you and ask you to read a script or do something you've prepared. good luck!!
