For those going to see the Doctor Strange movie (which is absolutely awesome, btw!) keep an eye out for some deeper Marvel Universe connections...
Rachel McAdams' female lead character is named Christine Palmer, who in the comics is the Night Nurse!
Before his car crash Strange is on the phone with his assistant and hears about an Air Force pilot who received spinal injuries whilst wearing experimental armor - this is a reference to Rhodey's injuries sustained as War Machine in Captain America: Civil War.
One of the Kamar-Taj sorcerers is named Tina Minoru - mother of Nico Minoru of the Runaways which is being adapted into a TV series. Tina also wields the Staff of One in the movie!
Another of the Kamar-Taj sorcerers is Daniel Drumm, brother of Jericho Drumm aka Brother Voodoo!
The film's main villain Kaecilius is based on an actual Marvel character from the mid 60s who was a minion of Baron Mordo!
Kaecilius' zealot Lucian is based on the 90s Marvel character Blackwulf.
During a fight with Kaecilius Wong wields the Wand of Watoomb!
