The official movie trailer for Tim Burton's Dark Shadows will debut on the Ellen DeGeneres Show on Thursday, but a few teaser clips and videos have emerged online based on footage from Ellen.

Warner Bros., who will release the trailer on Ellen and via Apple on iTunes, has also released the official website for the film, which will be in theatres and IMAX on May 11. The website has a countdown for the trailer debut on Apple in addition to social media information for the highly anticipated movie. The trailer for Dark Shadows will be released on Apple at 5 p.m. PST.

Some of the footage of the trailer emerged online thanks to an exclusive preview from the Ellen show. Johnny Depp, who plays vampire Barnabas Collins, and Eva Green, who plays vindictive witch Angelique Bouchard, are seen in an embrace and kiss and an intimate position. The flash to a shaking coffin, a young girl crying, Depp raising his arms and long finger nails vampire-style in the rain, and just like that, the three-second teaser is over.

Earlier this month, official cast photos were released depicting Depp as Barnabas Collins with his hands, fully equipped with long, pointy vampire fingernails, crossed at his chest. Costume designer Colleen Atwood paid homage to Jonathan Frid, the original vampire Barnabas Collins in the Dark Shadows series which ran between 1966 and 1971 on ABC. Depp wears the infamous ring and medallion worn by Frid as Barnabas as well as the pale makeup, medallion, collar and cloak.

The film stars Johnny Depp, Michelle Pfeiffer, Helena Bonham Carter, Eva Green, Jackie Earle Haley, Jonny Lee Miller, Bella Heathcote, Chloe Moretz, and Gulliver McGrath and is directed by Burton. The film is based on a 1960's gothic television soap opera and cult classic of the same name by Dan Curtis, adapted for the silver screen by Seth Grahame-Smith and John August. The plot is centered around the Collins family and their various run-ins with the supernatural, werewolves, witches and vampires and Barnabas Collins, a man turned vampire thanks to a vindictive witch Angelique Bouchard, originally played by Lara Parker.

The official film synopsis from Warner Bros. Pictures reads:

In the year 1752, Joshua and Naomi Collins, with young son Barnabas, set sail from Liverpool, England, to start a new life in America. But even an ocean was not enough to escape the mysterious curse that has plagued their family. Two decades pass and Barnabas (Johnny Depp) has the world at his feet -- or at least the town of Collinsport, Maine. The master of Collinwood Manor, Barnabas is rich, powerful and an inveterate playboy ... until he makes the grave mistake of breaking the heart of Angelique Bouchard (Eva Green). A witch, in every sense of the word, Angelique dooms him to a fate worse than death: turning him into a vampire, and then burying him alive.

Two centuries later, Barnabas is inadvertently freed from his tomb and emerges into the very changed world of 1972. He returns to Collinwood Manor to find that his once-grand estate has fallen into ruin. The dysfunctional remnants of the Collins family have fared little better, each harboring their own dark secrets. Matriarch Elizabeth Collins Stoddard (Michelle Pfeiffer) has called upon live-in psychiatrist, Dr. Julia Hoffman (Helena Bonham Carter), to help with her family troubles.

The official movie trailer for Dark Shadows will be released on Apple at 5 p.m. PST.
