What movie and television projects has David Ballantyne been in?

It seems there isn't a well-known actor or filmmaker named David Ballantyne with significant credits in film and television. It's possible there are several people with this name working in the industry, but without further information, it's difficult to determine their projects.

To help me find the right David Ballantyne, could you provide more context? For example:

* Is he an actor, director, producer, or something else?

* Do you have any other information about him, like his age, nationality, or any specific roles he may have played?

* Do you know the time period or specific projects he may have been involved in?

With more details, I can try to locate the correct David Ballantyne and find his credits.
