However, 27-year-old Zac seemed preoccupied as he lugged around a holdall and a rucksack, showing off his rippling muscles and bulging biceps as he went. 

Chloe was incredibly up-beat as she laughed and joked with the cast and crew during a moment of downtime, holding her phone in her hand and posing with her fists on her hips.

The teenage actress looked beautifully fresh faced in a white tank top, skinny jeans and zip-up hoodie.

The Kick-Ass star rounded off her laid-back look with grey pumps and dark sunglasses.

She wore her long blonde tresses in gently waves which cascaded down past her shoulders and didn't appear to be wearing any make-up.

Zac was dressed in an equally laid-back ensemble having teamed an orange T-shirt with back jersey shorts, stripy sports socks and scruffy trainers.

He looked ultra cool in a pair of aviator sunglasses and had his lips tightly pursed as he left his trailer strode across the car park with a refreshing bottle of water in his hand.
