I'm looking for an old movie called Inside Out. It was supposedly filmed in Old Chelsey Quebec Canada back in the 1960's.
My great uncle was in a scene in it.
Thank you for any help.

Are you sure of the title? I did several keyword searches on OCLC, a world database, but can't find it. Please call or visit a larger public library's reference desk and ask this question, giving them your great uncle's name to help their searching.

Here's Wikipedia's list of Canadian films, including from the '60s. Does any title look like the one you're asking about?
