That’s a lot of detail for one episode. Is it all told in exposition or are there flashbacks?
There’s a lot of pre-production involved in making a film; Your scene could have something to do with that. Makeup tests, wardrobe fittings (it could include an outfit-choosing mini game), and also forms and contract signings. If there’s any action, there could be a training session. Publicity photos (following the wardrobe and makeup approval), interviews for future special features, rehearsals, etc, etc. She could tour a set that’s been built already. There’s lots that goes on before principle photography begins.
