SLC Fanboys Tysen Webb & Andy Farnsworth got to watch the 15-minute IMAX 3D preview of "Doctor Strange" that Marvel showed to a handful of fans in October.  Benedict Cumberbatch tries out an American accent (for a change) as Dr. Stephen Strange, a neurosurgeon who goes on to become a Master of the Mystic Arts under the tutelage of Tilda Swinton's Ancient One.  Rachel McAdams and Madds Mikkelsen also star in the CG-heavy blockbuster. Andy & Tysen liked the humor and visuals they got to see, but was there a possible Marvel Cinematic Universe continuity error in the preview?
