How do I share a comfort film when my friends keep mocking it?

Ten minutes into the film, my friend started doing the lead actor's voice over the dialogue. Someone else joined in. I laughed once, then realised I hadn't heard the next scene.

We'd agreed to take turns bringing a film from our teenage years. Mine was a sentimental adventure I used to watch at sleepovers. I said it wasn't a masterpiece, and apparently that sounded like an invitation to spend the whole screening making fun of it.

I don't need them to love it. I do want to see it rather than listen to a new commentary track. When I asked for a quieter bit, my friend said the teasing was the fun of watching old favourites together.

Was I unclear about the sort of evening I wanted? I'd like to keep the film rotation, but not feel as though choosing something dear to me means volunteering it for a roast.
