More than 60 people injured in a terrifying crowd crush at last year's Falls Festival are taking the event organisers to court.

Nineteen people were taken to hospital with broken bones and other serious injuries and dozens more were hurt when a stampede broke out between acts in the Grand Theatre at the Falls Music and Arts Festival at Lorne on December 30.

A blocked-off entrance to the festival's Grand Theatre, where the crush happened.

A class action was lodged through Warrnambool law firm Maddens Lawyers in the Victorian Supreme Court on Wednesday.

Maddens senior partner Brendan Prendergast said about 65 people are on the statement of claim, but since news broke of the action, more people have come forward.
