Jake kept himself under wraps in a pale denim shirt and a pair of sunglasses, looking clean-shaven.

His mystery pal showcased her figure wearing a white vest top and a form-fitting yellow skirt, sunglasses shielding her face from the sun while her blonde locks flowed freely.

The identity of the companion is not known but the actor was rumoured to be dating his Constellation co-star Ruth Wilson, 34, although the pair never confirmed the claims.

The drama/thriller has an all-star cast, including Amy Adams, Isla Fisher, Kim Basinger, Aaron Taylor-Johnson, Ellie Bamber and Robert Aramayo. The movie is an adaptation of Austin Wright’s 1993 book Tony and Susan.

The story follows Susan Morrow (Amy Adams) who is sent a mysterious manuscript from her ex-husband asking for her opinion.

Susan becomes enthralled with the fictional life of the protagonist, Tony Hastings (Jake Gyllenhaal) and his wife Laura (Isla Fisher), and as both stories unfold, Susan is plunged back into her dark past.

Split into two parts, the second half of the movie follows Tony and his family vacation which takes a violent turn.

American fashion designer Ford wrote the script and will produce as well as direct the film.

This will be the former LFW designer's second foray into film direction, having debuted with A Single Man in 2009 for which Colin Firth received an Oscar nomination for Best Performance by an Actor in a Leading Role.
