Following the lead of Christopher Guest and his improvisatory style of filmmaking (Best In Show, A Mighty Wind), British film-maker Debbie Isitt uncorks the creative juices of her ensemble cast for this hilarious mockumentary of pre-marital jitters and strife.

Within the loose framework of the storyline, Isitt gave her actors scope to embellish and enrich their characters, ad-libbing with gusto to create a memorable menagerie of oddballs and misfits.

The cast nurtured their alter egos in improvisational workshops, remaining in character for the entire production period to ensure spontaneity and sustain the "reality" of the set-up.

More than 150 hours of footage was then pruned and polished into a compact 99 minutes. The result is a hugely entertaining confection, which, like the very best weddings, has tantrums, tears and blushing brides in abundance, not to mention flashes of nudity.

Confetti conceals its disjointed narrative behind the dramatic conceit of a reality TV game show.

When Confetti bridal magazine announces a competition to find "Most Original Wedding Of The Year", with a £500,000 dream home as first prize, couples from across the UK excitedly apply.

Egotistical publisher Antoni Clarke (Carr) and editor Vivienne Kay-Wylie (Montagu) choose their three favourites: hopeless romantics Matt (Freeman) and Sam (Stevenson) with their Busby Berkeley musical theme; professional tennis partners Josef (Mangan) and Isabelle (MacNeill) and their courtside ceremony complete with giant bouncing balls; and nudists Michael (Webb) and Joanne (Colman), who want to tie the knot au naturel.

Working with flamboyant gay wedding planners Heron & Hough (Franklin, Watkins), the three couples make preparations for their big days, aware that the judges are watching their every move.

Confetti has some wonderful touches of comedy and pathos.

A priceless moment is Josefs inept attempts to compose a love song for his fiancee, side-stepping a lyrical minefield by clumsily rhyming Maria Sharapova with the creatively misnamed Bosnia-Herzegova.

Watkins and Franklin are hysterical, playing arguably the most blissfully happy twosome in the entire film.
