I have been looking for an official HD file of this for years. I recently came across it to rent or buy in the UK via Microsoft’s official website: https://www.microsoft.com/en-gb/p/the-in-crowd/8d6kgwzl5j4q?activetab=pivot:overviewtab
This film has not had an official HD release in the US or Canada, to date. Just a HD airing on cable TV.
Please PM me if you think you can help. Cheers
