Tusk doesn't arrive in theaters until this fall, but director Kevin Smith is already thinking spin-off. According to Screen Daily, he's looking to do Yoga-Hosers, a spin-off of Tusk based on two characters you apparently see for only five minutes in that film.
It doesn't sound at all like a horror film as Smith said Tusk is part of a "horror trilogy" that began with Red State and will end with the forthcoming Anti-Claus (his Krampus film). What is known about Yoga-Hosers is this, according to SD:
A24 is handling Tusk's distribution.
In the film, Michael Parks plays a creep who lures Justin Long's character (a dude who runs a podcast) into his abode and then slowly turns him into a walrus. Genesis Rodriguez co-stars wth Haley Joel Osment.
