Daniel Radcliffe (5'4″) and Erin Darke (5'6″) – 2 inches:
Despite widespread hopes for an off-screen romance between Daniel Radcliffe and Emma Watson after their work on the Harry Potter franchise, Radcliffe found love with Erin Darke, who is two inches taller than him.
They initially connected on the set of the movie "Kill Your Darlings." Although their relationship blossomed, Darke did express concerns over Radcliffe's significant weight loss for his role in the movie "Jungle."
