"He became identified with the phrase "In a world…", used in so many movie trailers that it became a cliché. Widely known in the film industry, the man whose nicknames included "Thunder Throat" and "The Voice of God", became known to a wider audience through commercials for GEICO insurance and the Mega Millions lottery game.

"LaFontaine continued to work as a recording engineer after discharge and began working at the National Recording Studios in New York City, where, in 1962, he had the opportunity to work with producer Floyd Peterson on radio spots for Dr. Strangelove. Peterson incorporated many of LaFontaine's ideas for the spots and, in 1963, they went into business together producing advertising exclusively for the movie industry. LaFontaine claimed that this company first came up with many of the famous movie trailer catch phrases, including his own future signature phrase, 'in a world…' \
"With the advent of ISDN technology, LaFontaine eventually built a recording studio in his Hollywood Hills home and began doing his work from home."
" For a time, LaFontaine had a near-monopoly on movie trailer voiceovers. Some notable trailers which LaFontaine highlighted in the intro on his official website include: Terminator 2: Judgment Day, Shrek, Friday the 13th, Law & Order and Batman Returns. LaFontaine stated in 2007 that his favorite work in a movie trailer was for the biographical film The Elephant Man,[7] though according to a response to the question on his website, he had several trailers which stood out in his mind, and he didn't like to choose one.[8]"
"LaFontaine also did other voice work, including as the announcer for the newscasts on WCBS-TV New York, from 2000 to 2001. LaFontaine was a recurring guest narrator for clues on the game show Jeopardy![10] and appeared on NPR's Wait Wait… Don't Tell Me! on May 14, 2005, where he played "Not My Job" (a game in which famous people have to accurately answer questions totally unrelated to their chosen professions). The prize (for a listener, not the contestant) is "Carl Kasell's voice on your home answering machine". LaFontaine did not win the game, and offered to record the listener's answering machine message himself. LaFontaine once claimed that he enjoyed recording messages like these because it allowed him to be creative in writing unique messages, and said that he would do so for ANYONE who contacted him if he had the time. By 2007, he found the requests to be too numerous for him to take on, and stopped providing the service."[Emphasis mine]
Look at last sentence:
"In 2006, GEICO began an advertising campaign in which actual customers told their own stories of GEICO experiences, accompanied by a celebrity who helped them make the story interesting. LaFontaine was featured as the celebrity in one of these ads which began airing in August 2006. In the commercial, he was introduced by the voice-over as "that announcer guy from the movies", with his name printed on-screen to identify him. He began his telling of the customer's story with his trademark "In a world…". LaFontaine credited the spot as life-changing for having exposed his name and face to a significant audience, noting, 'There goes any anonymity I might have had…' "
DING DING DING!!!!!
"His final movie trailer voice-over was for Call + Response, a documentary about the global slave trade, for which he donated his talent."
