Curious for more? Then you already might have picked up the unrated version of February’s boxoffice favorite, Fifty Shades of Grey, which arrived on Blu-ray Friday. But just how different is it from the theatrical cut?

The new extended edition adds an extra three minutes and 16 seconds of footage to the opening installment of the planned trilogy charting the kinky romance between sweetly naive cardigan enthusiast Anastasia Steele (Dakota Johnson) and handsome young billionaire Christian Grey (Jamie Dornan). PEOPLE watched closely to discern key distinctions between the versions.

Learn about what all is different, including the biggest change, which comes at the end of the film.

Adapted from E.L. James’ erotic best-sellers, the big-screen series continues with 50 Shades Darker, set to arrive in theaters Feb. 10, 2017, with a script from James’ husband, writer Niall Leonard.
