Stewart remained in the public eye due to his frequent visits to the White House during the Reagan administration. The re-release of Hitchcock films gained him renewed recognition, with "Rear Window" and "Vertigo" in particular praised by film critics. Stewart also received several honorary film industry awards at the end of his career: an American Film Institute Award in 1980, a Silver Bear in 1982, Kennedy Center Honors in 1983, an Academy Honorary Award in 1985, and National Board of Review and Film Society of Lincoln Center's Chaplin Award in 1990. The honorary Oscar was presented by former co-star Cary Grant "for his 50 years of memorable performances, for his high ideals both on and off the screen, with respect and affection of his colleagues." In addition, Stewart received the highest civilian award in the US, the Presidential Medal of Freedom, "for his contributions in the fields of the arts, entertainment and public service," in 1985.
