(Random assortment actor au)Alternate final battle is a 10 minute outtake of everyone throwing hand props at Kira while he lays on the floor. Stray Cat is an animatronic (because unlike the stands, he interacts with props and such) and and most of the cast own plushie stray cats. Actor!Jotaro totally embraces the marine biologist jokes and has played Ocean man at con panels and stuff. Actor!Rohan is a pretty good artist; he really likes drawing Josuke and Jotaro "for purely aesthetical reasons"
Bonus: Everyone has sung the classic opening Great Days together at the end of a particularly grueling shoot and everyone sounds absolutely out of it and SOMEONE put it up on youtube
