The trailer for Blake Lively’s new flick looks positively TERRIFYING

So the first teaser trailer for Blake Lively's upcoming film the Shallows sure does succeed in piquing our interest. 

The movie stars Blake as a recently bereaved surfer who is left injured and stranded on a slab of rock just metres from the shore. 

Doesn't sound too bad? Yeah, just add a hungry, great white shark to the mix. 

Blake was spotted filming for the film on Lord Howe Island in Australia. She even brought hubby Ryan Reynolds and baby daughter James out for a little holiday while on location. 

The thriller is due to hit cinemas in June.
