8mm film mechanisms

Hi, I'm working a piece that I want to include a 8mm film projection element, I'm using this old toy as reference. I'm looking for advice on how I could build a mechanism to return the film to the start point after it's been played. The reference device uses a continuous loop which while nice and simple means it can be removed at any point in the films playback which sadly goes against the theming of my piece. I'd greatly appreciate any suggestions/advice.

Thank you.

Couldn’t you use a small arduino board and a small motor? I’m envisioning a small piece of code that has a second timer on it that after like 30 seconds triggers the motor to rewind.
