Many thanks to mattrprt who has shared two photos on webstagram here and here.
From a comment left on one of the photos, Jim Carrey is on set and filmed scenes with Louie Lopez as did Suki Waterhouse and Giovanni Ribsi. While we have not seen an announcement for Mr. Ribisi, he is in the cast.

Many thanks to tsbh for sharing a photo on webstagram. This photo has a “thebadbatch tag. Salvation Mountain is located near Slab CIty and the Salton Sea both of which are locations in the film. It is not clear if it will be used as a backdrop for the film.
