Who really directed Poltergeist (1982)?

Jobeth Williams: Steven was there every day. He had very clear and strong ideas about what he wanted done and how he wanted it done. Even though Tobe was there and participating, you felt Steven had the final say on everything.

Zelda Rubinstein: I can tell you that Steven directed all six days I was there. I only worked six days on the film and Steven was there. Tobe set up the shots and Steven made the adjustments.

Craig T. Nelson does defend Tobe, saying Tobe gave him "a lot of direction" (high praise for the sole credited Director), but even he says Tobe got pushed out in post-production.
