During the ceremony, the AMPAS gave Academy Awards (now commonly called Oscars) in twelve categories. Winners were announced three months before the live event. Some nominations were announced without reference to a specific movie. Examples were Ralph Hammeras and Nugent Slaughter, who received nominations in the now defunct category of Engineering Effects. Unlike later ceremonies, an actor or director could be awarded for multiple works in a year. Emil Jannings, for example, was given the Best Actor award for his work in both "The Way of All Flesh" and "The Last Command". Moreover, Charlie Chaplin and Warner Brothers each received an Honorary Award.
