About 10,000 people turned out to see X-Files star Gillian Anderson at Westfield Miranda in 1996.
Anderson, who played FBI agent Dana Scully in the sci-fi TV series, was welcomed on stage at 1.45pm by deafening screams from young fans.
Some of the crowd, who came from all over Sydney, had queued in the middle of winter from 2am.
Westfield later denied there were chaotic scenes and injuries.
Marketing manager Jordina Ross told Leader reporter Nerry Stark "only 10 people" had required treatment for heat exhaustion.
"Some members of the crowd became quite warm and jugs of water were passed by St John Ambulance and Westfield centre management staff to those in the front row at the stage," she said.
"There was no crush, no injuries and no complaints.
"We expected a crowd of thousands and we were prepared for it, with 20 police and 30 security officers on site.
"The crowd was well controlled and well behaved."
Anderson visited three cities in Australia to promote The X-Files, which was launched in 1993 and turned her and David Duchovny (agent Fox Mulder) into household names.
Westfield management said no other personality had attracted such large numbers to the Miranda centre.
The X-Files ran for nine series until 2002 and was revived in 2016 when Anderson returned for a further two seasons.
In 2018, Anderson was honored with a star on the Hollywood Walk of Fame.
