(C) within the scope of employment as a moving picture machine operator, assistant operator, usher, or ticket taker in a motion picture theater in connection with a motion picture film or show exhibited in such theater, if such operator or assistant operator has no financial interest in the motion picture theater wherein he is so employed other than his wages received or owed, and such person consents to give testimony regarding such employment in all judicial proceedings brought under this act, when granted immunity by the trial judge; or
