The Thor franchise has not been as big a success as other Avenger-led movies set within the Marvel Cinematic Universe. Both installments have had acceptable box office earnings and decent responses from viewers, but it has not yet had a smash hit. Marvel is doing everything in their power to turn this around for Thor: Ragnarok, as the cast is as impressive as any Marvel film in comparison. If Thor being the lone Avenger was not enough, this time he will have the help of Hulk, who has become a fan-favorite since Mark Ruffalo debuted in The Avengers.
Thor and Hulk will undoubtedly cross paths with Loki, Hela, Skurge, Grandmaster, and even Surtur in what has been described as an universal road trip movie. Even though Loki figures to be an antagonist throughout, recent set photos indicated a truce between the brothers to find an exiled Odin. The photos even indicated a possible appearance by one of the newer superheroes in the MCU, but director Taika Waititi is playing coy about this possibility.
In an interview with Digital Spy, Waititi was asked about the aforementioned set photo. In the photo, Thor is seen holding a business card that has 177A Bleecker Street written on it. For those unfamiliar, that is the address of the Sorcerer Supreme himself, Doctor Strange. Waititi says he does not know whether or not Benedict Cumberbatch will make an appearance in his film or not, indicating that it may have just been something done for eagle eyed fans:
"Ohhh I don't know. I am not sure if... I don't know actually. I can't comment on it. It may have just been something for the fans... Might be something like that. Might be a little tease. Or maybe a tease just for people who wanted to zoom into that photo."
There are two ways to look at this comment from Waititi. The first, and more fun, is that he is just hiding the fact that Cumberbatch does have a cameo in the movie. After all, Strange will definitely be involved in Avengers: Infinity War in some capacity, so he needs to get more connected with the larger universe. This could be something that happens at the end of Doctor Strange or the post credit scene, but either way Strange's appearance would be a fun moment for audience members.
The second way to look at these comments is to believe that this was just a tease for fans. The photo that revealed this was taken in a very public portion of filming with Hemsworth holding up the card in the perfect position to be seen by photographers. This would be a clever way to generate further talk around the film outside of just Hemsworth and Hiddleston on set together. The biggest problem with this interpretation is fans being let down if he does not appear, especially after hoping it would be the case for over a year. It would have been simple to squash this if it was just a rumor, but the fact that Waititi is letting the speculation continue seems to point to it being real.
