Personality cults involving stuff like T-shirts and ironic prayer candles seem much more usual for musicians -- I wonder why though.
This makes listeners feel they have a connection to who the musician actually is.
Actors, by the very core of their occupation, don't have that level of immediate authenticity.
There are movies that have affected me profoundly but I'd have to watch them again in the right circumstances and mood to even hope to be similarly affected a second or third time. But there are songs and albums that I'd argue will always get an emotional reaction from me barring some weird scenario where I had to listen to them on repeat for days until they were worn out.
