Dear Peter,
Our school is planning to hold an American Film Festival next month. I'm writing to ask you to come and give a talk on American films and filmmaking industry. It will help us understand how the industry has developed into big business as it is today. This understanding should go a long way toward increasing their knowledge of American culture in general. Do you think one and half hours will be enough?
Please let me know as soon as possible so that I can make arrangements. I'm looking forward to seeing you and enjoying the talk.
With best wishes,
书信体格式，按照邀请信的格式写，讲清你邀请对方的目的、要求等。
