Yes, you read that right, Samantha Jones herself is the narrator of How I Met Your Father. The Sex and the City veteran plays the future version of Hilary Duff's character, Sophie.
While that is similar to Bob Saget's role in HIMYM, who portrayed future Ted (off-screen, might we add), there is a twist; this time around, viewers are shown Sophie rather than her child.
In the year 2050, Sophie is telling the how-I-met-your-father story to her off-screen son. Though he insists he knows the story, Sophie chooses to recite the lengthy, more detailed version.
Plus, Sophie tells her son that "this story is about the journey, not the destination," so of course, he's in for a bunch of TMI moments and dramatic stories.
