Monster Island (2019)
Monster Island was the Asylum's 2019 mockbuster and it was released in the same period as Godzilla King of the Monsters. The film tells the story of a mysterious island in which a monstrous creature lives. In a way, the creature is the island.
To keep costs low, the film only follows a few human characters. All A-listers are on one set so they can shoot all their sequences while having lunch. But let's not forget that this is a kaiju film, and (link to info) that's basically of how those things work, so maybe The Asylum won't do too badly with it?
