David Slade about 'The Twilight Sage: Eclipse' trailer.

The Twilight Saga: Eclipse - Summit Ent.
Yesterday, we discussed the possibility of the first teaser trailer for The Twilight Saga: Eclipse being shown at the Academy Awards ceremony in March. One commentator suggested that it'd probably be released in conjunction with Robert Pattinson's Remember Me (also a Summit Entertainment picture).
Discuss though we might, the film's director (David Slade) has answered what is apparently a rather popular question by stating that he does not know when the first teaser trailer for The Twilight Saga: Eclipse will surface (via Twitter).
Overwhelming question I see again and again - When is the first trailer for Eclipse? I really don't know I am afraid.
I know they are working very hard on it. But I don't have any idea when it will be out.
Aw shucks, David.
At any rate, you also might be seeing a lot of "first of" headlines surrounding the first The Twilight Saga: Eclipse still frame image.
To answer a few of your questions, yes this picture did first make an appearance in the pre-The Twilight Saga: New Moon special edition of People Magazine.
It's been floating around for quite some time.
What is (sort of) new is the synopsis issued for the film:
* June 30, 2010* Action/Romance* Directed by David Slade* Screenplay by Melissa Rosenberg* Based on the novel “Eclipse” by Stephanie Meyer* Cast - Kristen Stewart, Robert Pattinson, Taylor Lautner, Ashley Greene, Billy Burke, Peter Facinelli, Elizabeth Reaser, Nikki Reed, Kellan Lutz, Jackson Rathbone and Dakota Fanning
In The Twilight Saga: 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 struggle between vampire and werewolf. With her graduation quickly approaching, Bella is confronted with the most important decision of her life.
