How much does the fictional Mary resemble the real actress? And how did she get the role?
There are some big differences between truth and fiction, of course. While Mary is new on the "Sherlock" scene, Abbington and Freeman have been in a committed relationship for over a decade. The two actors also have two children together and have worked on multiple acting projects over the years: "Men Only" (where they met), "The Debt," "The Robinsons" and "The Good Night."
Despite all that, the "Sherlock" wedding of John and Mary will be the couple's first -- the longtime partners have never tied the knot in real life.
