I own the American Lionsgate Blu-ray release of Vivarium. The main feature runtime is 98:37.
Also on disc:
Start-up trailers (6:43)
– Intrigo: Death of an Author
– Guns Akimbo
– Come to Daddy
My copy came with a slipcase and a code for downloadable Digital Copy (valid until May 12, 2021).
The extras are in HD (1080p24) and there are no subtitles for them.
