British actor Benedict Cumberbatch is expected to make an appearance in Thor: Ragnarok, the third instalment in the Thor film series starring Chris Hemsworth.

There are hints that the Sherlock fame star might join Hemsworth, Tom Hiddleston and Mark Ruffalo in the film as Dr Stephen Strange, a fictional character from forthcoming film Doctor Strange. 

A photograph from the Australian set of the film gave hints about his appearance. 

The images show Hemsworth in civilian clothes, and holding a business card with a handwritten address on it. It reads: "177A Bleecker St", reports 

It is the New York address of Dr Stephen Strange. The photographs were uploaded by a fan and later retweeted by the film’s director Taika Waititi.

There isn’t an official confirmation yet on Cumberbatch making an appearance in Thor: Ragnarok. There were also reports that actor Robert Downey Jr might also make an appearance in the film as Iron Man. 

Thor: Ragnarok will release in India on November 4. In addition to Hiddleston and Hemsworth, the film stars Idris Elba, Anthony Hopkins, Cate Blanchett, Jeff Goldblum, and Karl Urban.
