{{short description|Sound effect imitating the murmur of a crowd in the background}} {{Other uses|Walla (disambiguation)|Wallah}} {{refimprove|date=February 2023}} In American radio, film, television, and video games, '''walla''' is a sound effect imitating the murmur of a crowd in the background.<ref>Corey, M., Ochoa, G., ''The American Film Institute Desk Reference'', Dorling Kindersley, 2002, p206</ref> A group of actors brought together in the post-production stage of film production to create this murmur is known as a '''walla group'''. According to one story, walla received its name during the early days of radio, when it was discovered that having several people repeat the sound ''walla'' in the background was sufficient to mimic the indistinct chatter of a crowd. Nowadays, walla actors make use of real words and conversations, often improvised, tailored to the languages, speech patterns, and accents that might be expected of the crowd to be mimicked.
'''Rhubarb''' is used instead in the UK where actors say "rhubarb, rhubarb", '''''gur-gur''''' (''"гур-гур"'') in Russia, and {{nihongo||がや|'''gaya'''}} in Japan, perhaps in part reflecting the varying textures of crowd noise in the different countries. Other phrases are "peas and carrots", "watermelon cantaloupe", "wheelbarrow" and "natter natter" (to which the response is "grommish grommish").<ref>{{cite book|title=The Trouble with Tribbles: The Full Story of the Classic Star Trek Show|author=David Gerrold|publisher=Virgin|year=1996}} Refers to his own work as an extra, where he was taught 'natter' and 'grommish', before his writing career began.</ref>
