Judging by the quality, I’d say this film was made in the 70s. It’s about a large American family who all come back home to attend the funeral of the youngest member, a guy who killed himself. After the funeral, which happens early in the film, they all go home, and from there it’s basically one of those films where everyone’s thinking about their life choices, etc. There’s a bit of tension because they’ve all got their own lives and live in different states so they don’t see each other a lot.
Just to let anyone interested know that I finally found the film. The Big Chill (1983). Got a few things wrong. Sorry!
G;ad you found it and thanks for letting us know!
