The official word that The Twilight Saga: Eclipse had finished shooting came at 4:49 AM on October 29. David Slade posted the news via his Twitter account with this note: "Physically and emotionally exhausted."

No wonder. As with New Moon, the cast list for this Twilight sequel grew, adding more werewolves and vampires to Bella's ever-widening circle of friends and enemies. A guide to these new cast members follows. And if you're looking for a refresher, check out our previous guides: Meet the Cast of Twilight, Meet the New New Moon Cast ? Volturi, and Meet the New New Moon Cast - Wolf Pack.

BooBoo Stewart as Seth Clearwater

Where you've seen him: Small guest roles in episodes of several TV shows, including Everybody Hates Chris, Dante's Cove, and Blue Dolphin Kids

In Eclipse: As the younger brother of Leah and the son of Harry, Seth was always next in line for life as a werewolf. He fights alongside Edward and Jacob, and can pack a mean punch (or bite) when he needs to.

Verdict: He already has the happy Seth grin and russet-colored skin. We hope he has the acting credentials — oh, and fingers crossed, that he can howl.

Julia Jones as Leah Clearwater

Where you've seen her: Not in much. Her most substantial role was in ER, playing Dr. Kaya Montoya.

In Eclipse: Shock, horror: Leah's a werewolf, too. The only female wolf in the saga, if you want to get technical. She used to date pack leader Sam, and still hasn't gotten over his relationship with Emily.

Verdict: She looks the part physically and should compliment BooBoo Stewart well. Let's just hope they have good on-screen chemistry, or their brother-sister relationship could end up being more unbelievable than they'd like.

Jack Huston as Royce King II

Where you've seen him: In Factory Girl with Sienna Miller and Outlander. We're sure somebody, somewhere, will have heard of those.

In Eclipse: Royce King was the audacious, spoilt rich man engaged to human Rosalie Hale. On a drunken night out, he and friends beat and raped Rosalie before leaving her to die. Don't worry, though — Carlisle saves her, she gets her revenge, and Royce King II is never heard from again.

Verdict: He's got a smirk that screams arrogance and a Southern English accent to help him get into rich, upper-class mode. If that doesn't help him, nothing will.

Xavier Samuel as Riley

Where you've seen him: In Australian titles like The Loved Ones and 2:37

In Eclipse: Riley is, for lack of a better term, Victoria's newborn pet. He's part of her newly created gang, and is instrumental in bringing about the demise of Bella Swan. Luckily for us, he fails, and meets his end at the hands of young Seth Clearwater.

Verdict: He's young, attractive, and is sure to find himself with a female following. Rumor has it he's opening the movie and will be the first scene fans see. But no pressure or anything.

Jodelle Ferland as Bree

Where you've seen her: In far too many things to mention. Her most memorable roles are probably in the TV shows Supernatural and Kingdom Hospital and in the movies The Messengers and Good Luck Chuck.

In Eclipse: Bree is another newborn created by Victoria, and appears briefly in the third book. She surrenders herself to the Cullens, who give her a second chance of sorts. Luck isn't on her side, though, and Volturi guard Felix puts an end to her reign of undead terror.

Verdict: Bree is supposed to be around 15-years-old, so Ferland is probably the most accurate casting decision yet. And did we mention she can act? We can't wait to see her with blood-red vampire contact lenses.

Catalina Sandino Moreno as Maria

Where you've seen her: In Love in the Time of Cholera and Che Parts One and Two

In Eclipse: Maria, the leader of an all-female fanged trio during the Southern Vampire Wars, is responsible for Jasper's vampirism. Her whereabouts are still unknown, and the Cullens haven't heard from her since Calgary. Nice lady, eh?

Verdict: After seeing her in Che, we think she'll be up to the vampire challenge. As long as she remembers Maria's "musical voice," she'll be fine.

Kirsten Prout as Lucy

Where you've seen her: As Amanda Bloom in 43 episodes of the TV show Kyle XY

In Eclipse: Lucy was part of a trio of vampires during the Southern Vampire Wars. Together with Maria and Nettie, she put together a vampire army before eventually being killed by our very own Jasper Hale.

Verdict: Lucy is described as being "pale, tall, and blonde" — three boxes that Prout can easily tick. She has acting experience and a pretty hefty resume on her side, so her small part in Eclipse should be no problem.

Bryce Dallas Howard as Victoria

Where you've seen her: In Spider-Man 3, The Village, and Terminator: Salvation. Now, those are credentials.

In Eclipse: Victoria, queen of the vampire newborns, makes herself a brand new army. Hell-bent on killing Bella and avenging James' death, she ends up causing a war between the Cullens (who team with the wolves) and her newborns. Guess who wins?

Verdict: While the role of Victoria isn't new, Howard is. She has the extremely difficult task of filling Rachelle Lefevre's shoes — a casting change that shocked the Twilight world. Fans are loyal to Lefevre, and we're not sure what they'll make of Howard. Guess we'll all know their verdict next summer.
