J. J. Abrams - lens flare.
Michael Bay - explosions, explosions, and yet moar splodey stuff!
M. Night Shyamalan - twist ending.
Edgar Wright - foreshadowing/brick jokes (set-up lines early on that lead to a punchline much later)
Martin Scorsese: starting the film in the middle/end of the story before jumping back in time.
When I think of Edgar Wright I think of comedically over-the top, and mostly unnecessary, fast cuts (that make even mundane tasks, like making a cuppa, seem like a Jet Li fight sequence).
I'm not sure if it's a trademark or not but David Lynch's "Eraserhead" and "Elephant Man" both had loud urban/industrial noise as a sound track. I may have misremembered that but it felt like that. Not sure if this was a theme in any of his other films.
Note to self. I MUST watch Elephant Man again soon. It's one of the most beautifully shot films ever.
