## Set at summer camp
The film takes place at a summer camp, a setting that hands Birbiglia a built-in ensemble and a fixed stretch of time.
## Birbiglia wrote and directs
Mike Birbiglia is doing double duty as writer and director, so the voice on the page is the one steering the shoot.
## A crowded call sheet
Arnaud joins a previously announced cast led by Kathryn Newton, Lucas Hedges, Patrick Schwarzenegger, Geraldine Viswanathan and Dylan Gelula.
## Why the cast matters
Newton has Avengers: Doomsday, Schwarzenegger came off The White Lotus, Viswanathan was in Thunderbolts. Focus is stacking rising names.
## Key takeaway

Arnaud is the newest name on Old Friends New Friends, a summer camp comedy Birbiglia both wrote and directs.
