The Prestige (2006):
"After a tragic accident, two stage magicians engage in a battle to create the ultimate illusion while sacrificing everything they have to outwit each other."
Recommended, but you definitely understand more with a second watch. Good performances by Bale and Jackman as rival 1800s magicians. Plus, Nikola Tesla is played by David Bowie. Twist ending too! Watch it any way you can.
