There are many tales featuring a Prince Edward, and it's impossible to know who you're referring to without more context.
For example, are you referring to:
* A specific story or book? Please tell me the title.
* A specific film or television series? Please give me the title and year.
* A specific stage play? Please tell me the name and year of the production.
Once I have more information, I can help you find out who played Prince Edward in that particular tale.
