YAHOO.COM – The Seth Rogen-Zac Efron hit Neighbors was a crude, raunchy comedy riot, and it turns out there was even more crudeness and raunchiness left on the cutting room floor. In fact, director Nicholas Stoller shot two entire opening sequences that never saw the dark of movie theaters.

Both will be available on the Neighbors DVD and Blu-ray (available Sept. 23), and you can watch the first scene exclusively above. In the theatrical version, Efron and Dave Franco’s Delta Psi Beta fraternity has just relocated next door to Rogen, Rose Byrne, and family. We know they were kicked out of their previous house, but it’s never made clear what their infractions and/or indiscretions were.

The alternate opening scene above shows them, mid-party, rounding up the necessary booty (shrooms, cash, moonshine, a copy of The King’s Speech) to make an epic trade with a campus dealer. Spoiler alert: They’re buying military grade explosives, and what follows is an explosively funny fireworks display well worth the cost of house expulsion — or at the very least, a Blu-ray.
