HItchcock Advice

TO SPEAK OR NOT TO SPEAK?
“People don’t always express their inner thoughts to one another,” said Hitchcock, conversation may be quite trivial, but often the eyes will reveal what a person thinks or needs. “The focus of the image should never be on what is said, but rather on what the character is doing, unless it’s impossible to do so.” “We don’t have pages to fill, or pages from a typewriter to fill, we have a script, we need to have images on a rectangular screen in a movie house.” Sir Alfred Hitchcock

SUSPENSE IS INFORMATION
“Information” is essential to Hitchcock Suspense; showing the audience what the characters don’t see. If something is about to harm the characters, show it at the beginning of the scene and let the scene play out as normal. Constant reminders of this looming danger will build suspense (This can be done by Mickey Mousing the danger with music or etc.). But remember the suspense is not in the mind of the character. They must be completely unaware of it.

SURPRISE AND TWIST WITHOUT THE BOMB GOING OFF
Once you’ve built suspense it must never end the way the audience expects it to end. Lead them in one direction and make a u-turn at the last second and give them one Hell of a whiplash and a surprise twist.
