Your first kiss is always awkward.
You bang heads, clash teeth and, if you're going for the hat-trick, you bite your snogging partner's tongue (we've all done that right, RIGHT?)
While most of us get much better at this over time, imagine what it must be like for actors who have to kiss people on screen for the first time with a whole entire film crew watching them (and probably judging them) as they get involved with someone else's face.
Not only do you have to make sure that it looks good on camera, you also have to make sure it's realistic.
To prove that it's not always glamorous as it sounds, we've compiled a list of some of the most memorable kissing scenes on screen and what the co-stars had to say about it.
Thankfully there's no biting involved. Well, not that we know about.
