A movie depicting the romance between Prince William and Kate Middleton ahead of their April 28 wedding has been slated by critics as the ”worst royal film ever made.”

Kate & Wills airs on cable in America on Monday prior to being released on DVD and features New Zealander Nico Evers-Swindell and Briton Camilla Luddington, both of whom have minimal acting experience.

Costing $6.2m to produce the film is unlikely to give The King’s Speech any sleepless nights with The Sun’s critic castigating Swindell for looking more “red blooded than blue blooded” in his steamy scenes of passion.

Others voiced concern at the “cheesy” scenes  which depicted a fantasy interpretation of British life.
