The two-time Academy Award nominee is terminally ill with prostate cancer and unable to undergo chemotherapy, his attorney wrote in a Wednesday court filing. The ceremony was in front of the Egyptian Theatre.
Hopper received a best original screenplay Oscar nomination for co-writing the script of the 1969 counter-culture road movie "Easy Rider." His other Academy Award nomination came for best supporting actor for his role as an alcoholic father who becomes sober to be an assistant coach of his son's high school basketball team in "Hoosiers."
Hopper has appeared in more than 150 films.
Since 2008, Hopper has portrayed record producer Ben Cedars on the Starz series "Crash," continuing a television career that began with an 1955 appearance in the NBC medical drama "Medic." His other television credits include "The Twilight Zone," "The Rifleman," "Naked City" and "24."
He's also an accomplished photographer and painter. His photography has been displayed at The State Hermitage in St. Petersburg, Russia, The Manege in Moscow, the Stedlejik Museum in Amsterdam and The MAK in Vienna.
Hopper, 73, and his wife, Victoria, have been locked in a bitter feud since he filed to end the couple's nearly 14-year marriage in January.
He weighs barely 100 pounds and was described by his physician Dr. David Agus in the court filing as extremely weak and unable to carry on long conversations. The doctor added that he approved an appearance Friday by Hopper to receive the star on the Hollywood Walk of Fame because it is likely to be a positive experience.
Hopper filed a declaration last month saying he was undergoing promising chemotherapy treatments and remained hopeful "that this treatment will be successful so that I may soon resume the full enjoyment of my life and work."
