Eclipse opens in theaters on June 20th, and Summit Entertainment has released a new clip from the David Slade-directed entry in the Twilight Saga.

In Eclipse, Bella once again finds herself surrounded by danger as Seattle is ravaged by a string of mysterious killings and a malicious vampire continues her quest for revenge. In the midst of it all, she is forced to choose between her love for Edward and her friendship with Jacob- knowing that her decision has the potential to ignite the ageless struggle between vampire and werewolf. With her graduation quickly approaching, Bella is confronted with the most important decision of her life.

The new clip features an enraged Robert Pattinson grabbing Taylor Lautner by the throat and threatening violence... it's getting hot in here! Check out the clip below and see all of our Eclipse videos in the gallery!
