Some movie couples just don't have the right chemistry on screen. And even with some series, you've wondered: do these two characters have to be together?
Film and TV couples who didn't have the right chemistry
'Grey's Anatomy' is known and loved for its love stories. But we still don't understand the love affair between "George" (T.R. Knight) and "Izzie" (Katherine Heigl) - especially because the two of them had built up such a great friendship.
"Carrie Mathison" and "Nicholas Brody" from 'Homeland' were overall a good match. But there was absolutely no sexual tension between Damian Lewis and Claire Danes.
This was also the case with Robert Pattinson and Kristen Stewart in the 'Twilight' movies. Although the two were a couple in real life they could not score as such on the movie screen.
