Del Boy and the Queen have topped the list of most-booked look-a-likes after the demand for doubles quadrupled.
A surge in wedding bookings has also seen Prince Harry and Meghan soar to third and fourth in the rankings – pushing William and Kate out of the top 10.
As well as Only Fools and Horses legend Del Boy, other fictional favourites to leave party guests gawping are Pirates of the Caribbean’s Jack Sparrow and The Office’s David Brent.
Casting agent Helena Chard, of Susan Scott’s Lookalikes, says wedding pictures posted on social media are driving up demand.
She said: “We’re supplying far more lookalikes for weddings than ever before.

"Last year bookings were up almost 400 per cent, mainly due to a keeping up with the Jones’s mentality.
“People want bigger and better functions to rival their friends.”
Singer Ed Sheeran and celebrity chef Gordon Ramsay also make this year’s list – with footballer David Beckham sliding to No10, just behind Marilyn Monroe.
The trend is also a sign of couples taking more control of their nuptials, rather than relying on their parents.
But novelty guests do not come cheap. Fees start at around £300 per booking, with another £200 for props such as Del Boy’s van.
Helena added: “Years ago lookalike artists were booked mainly for high-profile corporate events. But they are now far more accessible.
“William and Kate are still booked for weddings – they’re the future King and Queen so they’ll always be popular.

“But Harry has the naughty boy image and everyone was rooting for him to get married. With Meghan too it’s a bit of Hollywood glamour.”
She revealed other favourites include Joanna Lumley and EastEnders’ Phil Mitchell, along with John Cleese, Dawn French and footballer Jamie Vardy.
The National Association of Wedding Professionals, which acts for wedding planners, says lookalike acts allow couples to put their own stamp on their big day.


Boss Siobhan Craven Robbins added: “More and more people are paying for their own wedding themselves, rather than relying on their parents.
“Therefore we see far more personalised touches such as booking lookalikes.”
But she urged people to take care to avoid any upset.
“We always advise people to get a contract, and make sure the act who is advertised is the same act who will be there on the day.”
