Sienna Miller, Abbey Lee and Kevin Costner couldn’t contain their laughter as they stepped onto the red carpet at the premiere of Horizon: An American Saga – Chapter 2 on the final day of the Venice Film Festival on Saturday.
The Western film was directed, produced and co-written by Kevin, who also stars in the film alongside Sienna, Sam Worthington and Jena Malone.
The first film was critically panned and failed to do well at the box office, so Chapter 2’s theatrical release was delayed indefinitely.
Sienna, 42, wore a sheer white jumpsuit with no bra, shorts underneath and a Chloe belt around her waist.
She completed her chic ensemble with knee-high black leather boots, while her blonde locks were styled in loose curls.

Actress Abbey, 37, showed off her stunning figure in a sheer lace dress with an embellished thigh-high slit skirt and nude shorts underneath as she posed for a series of stunning snaps at the event.

The Venice Film Festival kicked off on August 28 and by the end of Saturday, more than 20 films will have premiered in the Venezia 81 competition.
The film premiered on August 29 with the biographical psychological thriller Maria, starring Angelina Jolie.
Sienna and Abbey have been busy filming the third film in the Horizon trilogy: An American Saga, directed by Kevin.
Chapter 1 premiered at the Cannes Film Festival in May and in U.S. theaters the following month.

Chapter 1 was a box office flop and failed to recoup its budget, but Warner Bros. Pictures is hoping the next two films will turn that around.
Horizon chronicles a multifaceted 15-year period of expansion and settlement of the American West before and after the Civil War.
The films feature an ensemble cast and also star director Kevin, Sam Worthington and Luke Wilson.
A chapter 4 is confirmed to be in development.
