Comedian Billy Crystal will serve as the sole host of the 1990 Academy Awards broadcast, the Academy of Motion Picture Arts and Sciences has announced.

It will mark the third consecutive awards show appearance for Crystal and his first as host. The single-host format returns after 1989's ill-fated multihost show, which featured Rob Lowe and an unauthorized Snow White impersonator."We are extremely pleased to have Billy host the show," Gilbert Cates, producer of the 1990 telecast, said in a statement. "His unique talents and his ability to handle the unexpected will be important assets this year."

Nominations for the 62nd Annual Academy Awards will be announced on Wednesday, Feb. 14. Among the films in contention is the comedy "When Harry Met Sally . . . ," in which Crystal co-stars. The Oscar trophies will be presented at the Los Angeles Music Center on March 26.
