Kissing a co-star can be lots of fun despite what many actors say, especially if he or she is good-looking. Well, there is no doubt that Kirsten Dunst is gorgeous, but that wasn't enough for Tobey Maguire to be over the moon when he found out he had to kiss her in the extremely successful “Spiderman” movie they both starred in. The problem for Tobey was that he had to kiss Kirsten while hanging upside down, which meant blood was rushing to his head. If that wasn't enough, it was raining in the romantic scene, which means Tobey had water running up his nose too! Kate Hudson and Dane Cook Many actors find being on set an extremely hilarious experience, and it looks like that is the case with the gorgeous Kate Hudson. While filming “My Best Friend's Girl”, Kate would repeatedly eat a handful of onions right before filming every single kiss scene in the movie with actor Dane Cook. He complained about it in almost every interview they did to promote the movie, but it was all said in a friendly manner. Kirsten Dunst and Brad Pitt Who wouldn't want to kiss Brad Pitt? Apparently, Kirsten Dunst! She often declared that she was disgusted at the idea of kissing him when the two filmed “Interview With The Vampire” in 1993. But then, she was just 11 at the time which means that he was her first kiss and she admitted she didn't understand what all the fuss was about. Tom Cruise and Thandie Newton Is there anything more embarrassing than finding out your co-star doesn't want to kiss you because your kisses are too wet? Well, that is what Thandie Newton said about Tom Cruise after the two finished filming “Mission Impossible 2”. Reese Witherspoon and Robert Pattinson Reese said after she finished filming “Water For Elephants” with Robert that she didn't want to kiss him because he had a massive cold and snot was dripping down his nose constantly.
