Jamie Campbell Bower thinks teenagers need movies they can ''identify'' with.

The 24-year-old actor can understand why his latest film, supernatural saga 'The Mortal Instruments: City of Bones', has been compared with the 'Twilight Saga' franchise - in which he also appears - but insists that is just because they explore similar themes which are relevant to their target audience.

He told Event magazine: '''The Mortal Instruments' is not 'Twilight'. There are similarities like vampires, werewolves and a love triangle, but love triangles have existed throughout history, in literature and movies.

''It's never been easy being a teenager emotionally and hormonally, so it's really important for them to have movies like this that they can identify with.''

Jamie - who is dating his 'Mortal Instruments' co-star Lily Collins - also admitted he is grateful for the support of his parents, particularly when he dropped out of private education to pursue his dream.

He said: ''I dropped out of my A-levels because I started to act. 'Sweeney Todd' with Johnny Depp was my first film, and I chose not to go back to school.

''My parents could have gone, 'Are you mental? We put so much effort, time and money into your education.' But they were very supportive.''
