To top it off, the film barely recouped the star's salary-- earning just $26 million at the box office. According to Forbes, for every $1 Heigl is paid, she earns film studios just $3.40.

Earlier this month, Forbes named Eddie Murphy the "Most Overpaid Actor in Hollywood." Murphy may be worth a reported $75 million but he starred in one of the biggest flops of 2012. "A Thousand Words," which cost $40 million to produce but grossed just $18 million. It also was one of the lowest-rated films on Rotten Tomatoes in 2012. Furthermore, "Tower Heist," a film with a production budget of $85 million, took in just $75 million.

While stars like Robert Downey Jr, Kristen Stewart, and Channing Tatum proved capable of pulling their weight at the box office this year, 2012 also revealed that some stars just aren't worth their massive salaries.
