Roger Ebert won the Pulitzer Prize for criticism in 1975
Film critic Roger Ebert is becoming an honorary life member of the Directors Guild of America.
The film-makers' union's president, Michael Apted, praised the 66-year-old's contribution to Hollywood.
"From the blockbuster to the tiny independent film, Ebert has devoted his career to sharing his love of film with generations of moviegoers," he said.
The Pulitzer Prize-winning critic will receive his honour at the guild's award dinner in January.
Apted said Ebert had kept directors "on their toes for more than 40 years".
Ebert, who has been the Chicago Sun-Times film critic since 1967, is best known for his movie critic double act with fellow reviewer Gene Siskel, who died in 1999.
The pair famously used a "thumbs up" or "thumbs down" system to rate the films they saw.
Ebert has battled cancer and undergone surgery that has left him unable to speak, but he continues to write film reviews.
