During the ceremony, AMPAS presented Academy Awards now colloquially known as the Oscars in 12 categories. Winners were announced three months before the live event. Some nominations were announced without reference to a specific film, such as for Ralph Hammeras and Nugent Slaughter, who received nominations in the now-defunct category of Engineering Effects. Unlike later ceremonies, an actor could be awarded for multiple works within a calendar year for the same category. Emil Jannings, for example, was given the Best Actor award for his work in both "The Way of All Flesh" and "The Last Command". Also, Charlie Chaplin and Warner Brothers each received an Honorary Award.
