10 Movies Everyone Confuses With Other Movies

10. No Strings Attached & Friends With Benefits

If you can tell these two 2011 rom-coms apart, give yourself a firm pat on the back.

Released just six months apart, No Strings Attached and Friends with Benefits both follow two sets of young, attractive people who enter into no-strings sexual relationships without any interest in committed romance. Inevitably, feelings abound.

To make matters more complicated, the films star Natalie Portman and Mila Kunis respectively - who, in addition to looking alike, co-starred together in Black Swan the year prior - while their romantic partners are played by the not-that-dissimilar Ashton Kutcher and Justin Timberlake.

Tellingly, No Strings Attached was originally written under the title Friends with Benefits, but changed after the producers realised a "rival" project was in production.

Ultimately both films scored mixed reviews from critics but performed well at the box office, yet are ultimately such beige, forgettable rom-coms based on a similar premise that it's extremely difficult to tell them apart without a quick Google search.
