The park is officially open.

Excuse us while we explode with fanboy/girl glee at the first official trailer for Jurassic World, the hugely anticipated follow up to those other 'you may have heard of them' massive Jurassic blockbusters.

Chris Pratt takes centre, smouldering stage in the first action-packed trailer - and it looks like those rumours of genetically modified monsters are true.

The T-Rex ain't lookin' so scary now, is she?

Jurassic World will be released in 3D in June 2015.
