11. Cleopatra
These “Cleopatra” co-stars hated each other when they first met on set. But after being forced to kiss for a moment in the movie, they fell in love. Elizabeth Taylor famously married her fourth husband, Eddie Fisher, a couple years prior to filming started for “Cleopatra” in 1961. While filming, tempers flared between Taylor and Burton, Taylor calling her co-star “brutish and boorish”. But that passion quickly became romantic once they filmed their kissing scene. Supposedly, the director called cut and the two kept kissing. Once the actors’ significant others learned about the scandalous kiss, however, they filed for divorce. The love-hate passion between Taylor and Burton continued; they got married in 1964, divorced in 1974, remarried in 1975, and divorced again a year later.
