Phoenix's work encompassed 24 films and television appearances, including the science fiction adventure film Explorers, the coming-of-age film Stand by Me, the action sequel Indiana Jones and the Last Crusade and the independent adult drama My Own Private Idaho. Phoenix's meteoric rise to fame led to his status as a "teen sensation".
Phoenix began acting at age 10 in television commercials. He appeared in diverse roles, making his first notable appearance in the 1986 film Stand by Me, a hugely popular coming-of-age film based on a novella by Stephen King.
