10 Movie Trailers Released BEFORE FX Was Added

10. Ghostbusters II

One of the most memorable sequences from Ghostbusters II sees the titular ghost-hunters facing off against the ghosts of two executed murderers, the Scoleri Brothers, in a courtroom.

It's a wild scene jam-packed with imaginative visual effects, such that it's not terribly surprising they weren't anywhere close to completed when the film's first trailer was released.

The trailer shows some scattered glimpses of the brothers wreaking havoc, though one notable shot appears without any substantial effects elements - the prosecution lawyer (Janet Margolin) is grabbed by her leg and dragged out of the courtroom by a ghost.

In the final film the ghost is prominently visible throughout the lengthy shot, but in the trailer image we can simply see actress Margolin - or her stunt double, more likely - being pulled along, presumably by a stunt cable.

Thankfully in this case the omitted effects still kinda work, because it's still clear that she's being dragged around by a supernatural, ghostly entity, even if we can't see it. Clever.
