Cooper has claimed his greatest influence in his choice of profession is Stephen Frankfurt’s opening title sequence for To Kill a Mockingbird (film) . Cooper also pulls inspiration from William Shakespeare – his former production company, Imaginary Forces, takes its name from a line in the prologue of Shakespeare's Henry V (play) . The idea to name the company after this prologue is based on the idea that opening titles often act like a prologue to a film. This of course can also be seen as an influence for his current company, “Prologue”. All that said, Wired (magazine) notes Cooper isn’t typically hired due to a signature “style”. He’s hired to "dig under the celluloid and tap into the symbolism of a film".  This was a precedent he started with some of his earliest work, notably Seven (1995 film) .
