Acting out make believe characters is what actors do. So, if they are cast in a TV show alongside another actor that they are “supposed” to be in love with, they get on with the job of acting.

A TV couple spends long hours together on set– they are thrown together constantly, there are countless love scenes, there are bust ups, and there are occasionally fun times. Sometimes the two actors involved fall in love in real life, while other times they become friends.

What’s the worst that can happen? Well, the worst that can happen is that they don’t get on, argue and grow to hate one another. There’s a problem, though, since they are supposed to be in love, and this can hinder the tension between their characters.

The true professionals grin and bear it. They keep acting and doing their job, even if they don’t like it. Other times, actors whinge and demand their their TV significant other be written out of the show or replaced, or that their scenes together be limited. Some actors who hate their co-star have been known to walk off their shows, throwing things into total chaos.

Here are 15 TV Couples Who Actually Despised Each Other.

15. Mulder And Scully – The X-Files

Mulder and Scully hate one another? The answer to that seems to be yes. Back when the original series of The X-Files was airing in the 1990s, Mulder (David Duchovny) and Scully (Gillian Anderson) were victims of the show’s success.

They were forced to work long hours in close proximity. As the fateful saying goes: familiarity breeds contempt. Duchovny has gone on record saying that there were times when they were so sick of one another that they fought constantly and got to the point where they could not stand to be in the same room together. \

While the intimate relationship between Mulder and Scully is not heavily emphasized in the plot lines, it is always in the background of the show. Even though Duchovny and Anderson could not stand one another, the chemistry between their characters is skillfully maintained by two talented actors.

Still, it’s hard to imagine the arguments and tension that went on when the cameras weren’t rolling. Apparently, things were less tense when the duo filmed the reboot of the series in 2016. Fans were delighted to learn that the show would return mid-season in 2018.

14. Puck And Santana – Glee

Mark Salling and Naya Rivera hate one another. Their characters on GleePuck (Salling) and Santana (Rivera) have an on-again-off again, love-hate relationship that is always interesting to watch.

In real life, Salling and Rivera were involved in a relationship during the first season of the show. It seems that their turbulent on-screen relationship mirrored their off-screen one. After the first season wrapped and the cast went off on summer break, Salling began “cheating” on Rivera with other women.

Rivera responded by keying and egging his Lexus, which pretty much meant that the love-hate relationship was now permanently based on hate. After that, the writers made certain that the two had few scenes together.

Almost no one saw what was coming next: in 2015 Salling was arrested on child pornography charges. The one person who clearly was not shocked was Rivera. She has gone on record saying that after her experiences with Salling, she was not at all surprised.
