Mr Lea, a past Tararua district deputy mayor, said the idea of holding a gala event fundraiser for the premiere was generated between himself and his two brothers, Peter and Bruce, who serve respectively as the president of the Pahiatua Repertory Society and cinema manager.
"We were offered The Hobbit for a day and date screening - which is a first ever for the theatre - and the idea for a fundraiser just sprang from there."
Mr Lea said about 100 dignitaries have been invited to the premiere, including Tararua district Mayor Roly Ellis, district councillors and representatives from the business community.
Each of the dignitaries would assume the mantle of a Hollywood star and would gather in the green room at the rear of the building ahead of the premiere's official start.
Luxury vehicles including a pair of Cadillacs from 1960 and 1961 will ferry the dignitaries round the block to the front of the theatre, where media representatives and repertory society members posing as paparazzi will snatch photos and quotes from the assembling Hollywood elite.
The celluloid "stars" will be ushered on arrival into the downstairs area of the theatre, Mr Lea said, where they will enjoy champagne before the screening.
Tararua District Council communications and marketing manager Lianne Simpkin said the luxury cars belong to a business launching in Dannevirke, Timeless Tours, and other northern Wairarapa businesses and the council were also supporting the gala event.
