London, (Agencies): The nine-year-long romance between Prince William and Kate Middleton culminating in a much-publicised royal wedding is set to be turned into a TV movie.

The movie made by US TV network will chronicle "the ups and downs of their nine-year courtship complicated by social and royal family pressures", said producers.

William’s role will be played by actor Nico Evers-Swindell, while British 'Chariots of Fire' actor Ben Cross will play Charles. The role of Kate Middleton has yet to be cast.

It is likely to be aired in the week before the royal wedding on April 29.

The network said it would also address the "intense global media attention surrounding their storybook nuptials".
