At this year's San Diego Comic Con 2014 event, 'Teenage Mutant Ninja Turtles' Stars Will Arnett and Megan Fox, along with director John Liebesman, promoted their upcoming August 8, 2014 film.

In an interview with Comic Book Movie, the three of them offered fans behind-the-scenes information concerning the film's character relationships. Arnett began by explaining how his character, Vernon Fenwick, opposes Megan Fox's April O'Neil, but that they will come across supporting each other in the film.

Will 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."

The 'Arrested Development' actor made it clear that the story has evolved over the years. He mentions that a new direction had to have been taken to make it different from all the other mediums of the 'Teenage Mutant Ninja Turtle' series.

"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," said Arnett.

Megan Fox jumped in to talk about her character's involvement with the popular crime fighting reptiles in the film, without revealing too much, "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."

As 'Teenage Mutant Ninja Turtles' remains set for an August 8, 2014 release date, for now, fans can enjoy the trailer below:
