I am writing a pilot for a TV Series, and wondered if it may be legally possible to write in a character from another (relative) series?
This isn't it, but for example:
If I was to write about an Agatha Christie character who knew Miss Marple, and references were verbally made to her, could Julia McKenzie legally appear in an episode of mine, AS Miss Marple? And how would I go about getting the permission to use that visually conceived adaptation of her from ITV/Production Company (and of course with Ms McKenzie's approval too of course)?
