Abel also does have a pre-existing relationship with A24 from Uncut Gems (although his role was small). Keoghan has a relationship with Searchlight and Disney via Marvel, but he isn’t near the Star that Abel is.I think with a trio like that it could easily be bought by a larger group--but A24 would make a lot of sense if it's piggybacking off of the collaboration of The Idol.
The other thing, albeit in the sense; is how will be different than The Idol--which atleast in my eyes: looks to be tackling exploitation, toxicity and the rise of artists and figures within Hollywood as they try to stand out amongst themselves. Maybe given the nature of the three actors, we might be getting a story on romantic relationships, cheating and how people react to being cheated by?
If Abel is a producer, my bet is on this going to A24, but I also think this will be a highly sought after project that will be cheap to make and probably make a decent amount of money.
On the other hand, House Of Gucci, which had Gaga (coming of A Star Is Born in her acting career) among other high profile stars only made $53M and either barely broke even or lost money.
With that in mind, I think a low budget Searchlight film could be best bet. Disney will pony up for film distribution and marketing more than A24 can afford and Searchlight knows how to make award winning/nominated content just as much as A24 does.
