Marvel Studios always packs plenty of Easter eggs into its movies. Some of them are nods to the comics or other franchises altogether, while others actually hide the movie's ending in plain sight.Such is the case for a newly discovered Doctor Strange Easter egg. The Movie Details Twitter account shared a picture taken from the Scott Derrickson film's first act. It features Benedict Cumberbatch's Stephen Strange looking at his watch, but what's most notable on the watch isn't the time -- it's the date. In fact, the watch indicates the date is February 2.RELATED: Is Doctor Strange in the Multiverse of Madness More Literal Than We Think?As the Movie Details tweet reminds us, February 2 is also known as Groundhog Day.Groundhog Day is also the title of a classic film starring Bill Murray about a man reliving the same say over and over again. Given that the ending of Doctor Strange sees the Sorcerer Supreme trap Dormammu in an endless time loop, it's now clear that the Groundhog Day Easter egg discreetly gave away the film's ending.
