So, lets see
Just putting down some facts
- Robert Downey Jr portrais Tony Stark aka IronMan since 2008. He is also Sherlock Holmes in the 2009 and 2011 movies of the same name
- Rachel McAdams portrais Irene Adler in the 2009 and 2011 Sherlock Holmes movies. She will also appear as Christine Palmer in the 2016 movie Dr Strange
- Benedict Cumberbatch plays Sherlock Holmes in the BBC show Sherlock since 2010. He will be Dr Stephen Strange in the 2016 movie Dr Strange
- Rachel first played Robert´s love interest, now she´ll be Benedict´s
- RDJ and BC both play main characters in Marvel movies and were/are the character Sherlock Holmes in different
productions
Idk, wouldn´t it be funny if they all had a scene together in Dr Strange? It just seems funny to me.
