Answer:
Jim Carrey , in full James Eugene Carrey, (born January 17, 1962, New Market, Ontario, Canada), Canadian American comedian who established himself as a leading comedic actor with a series of over-the-top performances and who won plaudits for his more-serious portrayals as his career progressed.
Carrey grew up in and around Toronto. At age eight he began making faces before a mirror and discovered a talent for doing impressions. After leaving school in 1978 to help support his family, Carrey worked for two years as a janitor in a factory. He made his professional debut as a stand-up comedian in a Toronto club at age 15 and by 1979 he was able to make a living as a comedian. He wrote most of his own material as an opening act for such comics as Buddy Hackett and Rodney Dangerfield. Known for his racing energy level and frenetic improvisation, he had a comic appeal that was mainly visual. He was a technically brilliant mimic and boasted more than 100 characterizations, with a repertoire ranging from Humphrey Bogart to Kermit the Frog.
