And this week has seen the first glimpse at the stars filming in Vancouver while fully made up in costume.
In both, he is clean-shaven and blonde, but has obviously undergone an intense transformation to become the fifth heir to the throne.
Parisa meanwhile, who will be playing the 36-year-old future royal, has most-often been spotted with her thick dark curls, most recently seen in her role on Netflix’s Marvel series Jessica Jones alongside Krysten Ritter.
Murray sports a smart black and white suit, and can been seen grinning wrapped up in a large red winter coat to brave the Canadian weather.
Parisa looks every bit as glamorous as the real-life soon to be Princess, dressed in a flowing pillar-box red knee-length dress.
The actress’ hair appears to be shielded under a bouncy brunette wig, with a parting designed just-so to emulate the Suits star’s own lustrous tresses.
Added touches include a dusting of freckles across Parisa’s cheeks along with two dainty rings on her right hand.
Paris is also huddled under an extra layer to ward off the bitter cold in between takes, in the form of a short black puffa jacket.
When the Vancouver scenes are completed, production will then move on to Los Angeles for the remainder of the scenes.
The film will depict Prince Harry, 33, and Meghan’s love story from the very beginning before they met in 2016.
The couple have already revealed how they were initially set up by a mutual friend, and it blossomed from there.
The film will also focus on Meghan’s struggles with the press and international media after being thrust into the limelight.
The newlyweds will then go on to a reception at St George’s Hall before having their own private celebration with their family and close friends with The Prince of Wales, Prince Charles.
