There's one particular scene in the movie "Wolves of Wall Street" which doesn't "add up".  Picture the following:

• A "broker" "cold calls" a potential "client" to sell "stock".
• The "broker" is surrounded by coworkers who are "making noise".
• It's implied that the "noise" influences the "client" into purchasing said "stock".

Was that how it actually happened or did "movie makers" know the truth?

They did or didn't.

The "noise" may or may not have been previously recorded as "back-masked" "suggestion".  It may or may not have been part of every "cold call".  Each coworker making calls certainly wasn't taking advantage of it.

Backward or "well given loss".
