Casting problems

Today we were informed that Phil who was originally always going to be the main character will most likely not be able to be in it . We looked through a list of teachers at the school which included a photo of them all . We looked for teachers which we thought would fit our characters perfectly . We came to the end of the list with our own little list of teachers that could work . At the top of our list was a teacher from art , we asked him about dates and whether he would be available , which he wasn't due to January art exams. We then went to confirm with our actress that she would be available , sadly we were informed she wouldn't be able to make time for it . We had a serious problem , we had no actors . We looked to Phil for ideas on who too look to for casting , he gave us a few ideas of people that suited the part and may have time but told us to leave it to him . Otherwise we've confirmed our two locations , props and storyline.
