New Zealand actor Sam Neill was also honoured at the event with the Longford Lyell achievement award and appeared visibly emotional after film legends Meryl Streep, Jane Campion, Nicole Kidman, and Liam Neeson offered filmed tributes.
"The lifetime thing sounds a little terminal and I hope they don't mean it's the end because I'm not done, I would still like to put a few more runs on the board," Neill said upon accepting the accolade.
