Greta Glarn

Greta Glarn is an NPC that was introduced in The Sims: Superstar. She's one of the Studio Town movie directors. She will direct either an emergency scene or death scene in the staircase set only if your sim has 4.5 stars in their fame career, otherwise she will shoo you away.

Greta seems to be somewhat more short-tempered than the hospital set director, often getting angrier than the hospital set director if the sequences are chosen wrong.
