Justin Lee Collins's agent, Peter Bennett-Jones, has described his client as "an extraordinarily polite individual professionally".
Mr Bennett-Jones added that Collins had a "polite, respectful nature with everybody he has worked with".
"The behaviour I have read about and has been reported is inconsistent," he said, but acknowledged that he had not heard the recording of Collins's row with Ms Larke.
The trial will resume at 10am tomorrow when counsel will make closing speeches and Judge John Plumstead will sum up.
