Director: We have to get someone else for this part, they can't even get a simple kissing scene right.
Producer: Right, didn't we try to get Judith Ward for ....
Director interrupts: I'll call her agent.
They don't ask for reasons, they just want their movie done. Afraid you weren't quite what they were looking for. Back to auditions you go!
On a more serious note, no idea how many times my female, straight actress had to kiss Venessa Jeong, because she was always picked for those scenes, while the male co-actor were picked for any other scene. We do the job or we don't. Acting isn't for everyone.
