This originated on Hulu (where they had a commentary) so no US disc release. There's been a release in Germany, Italy, Spain (best artwork for me), Finland, Sweden and an arm-and-a-leg priced LE in Japan.
Never heard of Cristin Milioti but she's very good here. Andy Samberg was good too not seen him since the brilliant Hot Rod. J.K. Simmons is on Colombian marching powder as usual.

I've bought the Germany release:
'There's certain things in this movie that are not meant to be known with certainty,' Andy Samberg says in Hulu's new commentary cut of 'Palm Springs.'
