Donostia-San Sebastian International Film Festival director Mikel Olaciregui has warned that the festival calendar is overcrowded.

Speaking during the opening weekend of the event, he told reporters that his $7.8m (Euros 6m) budget - reportedly half thatof the new Rome Film Fest - didn't stretch to private jet-type expensesincreasingly required by top international stars.

"It's not easy to bring a star at a time when there isa saturation of festivals," Olaciregui added, calling on the FIAPF to getinvolved in regulating the pile-up of fall festivals.

"On an internationallevel the presence of so many festivals is insane'there simply cannot be afestival every week."

Given the difficulties, by Sunday the coastal town had welcomed a healthydose of talents including Clive Owen, Steve Buscemi, Jonathon Demme, BobcatGoldthwait, Alfonso Cuaron, Alejandro Gonzalez Inarritu, Tom DiCillo, MelindaPage Hamilton, Bruno Ganz, John Boorman, Brendan Gleeson, jury president JeanneMoreau, retrospective subject Barbet Schroeder and Donostia prize-winner Maxvon Sydow.

Producer Agustin Almodovar picked up the FIPRESCI Grand Prix Awardfor his brother Pedro's film Volver on Thursday night.

The line-upwas also receiving high marks. San Sebastian regular Carlos Sorin'sArgentina-set competition title El Camino De San Diego received a lukewarmresponse from local critics, following strong reviews for opening film Ghostsfrom the UK's Nick Broomfield, Heddy Honigmann documentary Forever about Paris'Pere Lachaise cemetery and especially comedies Vete De Mi and SleepingDogs Lie.

"Ahappy oasis in an irritable and cruel world," one critic wrote of thelatter two.
