SDCC 2014: 'Teenage Mutant Ninja Turtles' Movie Stars Megan Fox And Will Arnett Promote Film At Comic Con (PHOTOS/TRAILER)

Megan Fox, Will Arnett and director John Liebesman made the San Diego Comic Con rounds to promote the upcoming “Teenage Mutant Ninja Turtle” movie.

During an interview with Comic Book Movie, the trio shared behind-the-scenes details and information about character relationships. Arnett explained his character Vernon Fenwick is rivals April O’Neil (Fox), but it won’t be so black and white in the film.

“There has been through all the various incarnations - from the comic, to the TV series, to the movies - there have been creative and artistic licenses taken in order to tell whatever particular story and I think that as this movie really evolved and before we started shooting,” Arnett said.

“It became apparent that there needed to be an evolution and the character that they needed to partner up and support April,” he added, “they needed a character more like Vernon and they had to change the rules a bit with him. What is true with him is that he is a camera man, that part of it stays very true, but now he kind of works with April and some of his crankiness has been transferred into that he’s looking more for an easy ride… And then he gets sucked in.”

Fox also attempted to explain April’s connection to the TMNT crew without giving away too many spoilers. April was always suspicious of her father’s experiments and never trusted what he told her. However, it isn’t until her father’s death where the pieces start to come together.

“She loses him and it’s not until she starts hearing their names when she meets them on the roof that things start firing off,” Fox told Comic Book Movie. “[April] digs through all of her father’s old lab notes… and she discovers that these quite possibly are the little turtles that she used to look at in his lab before it burned down.”

“Teenage Mutant Ninja Turtles” will be released to theaters on Aug. 8.
