David Harbour spoke exclusively to PEOPLE about a 'very irresponsible' day on set while shooting a 'Stranger Things' scene alongside his costars Millie Bobby Brown and Finn Wolfhard during the show's season 5 premiere.

Thursday's premiere event brought the entire cast and crew together at Hollywood's Grauman's Chinese Theatre in Los Angeles.

The estimate was buried in a disclosure document obtained by Rolling Stone and made public Wednesday in Lively's ongoing sexual harassment and retaliation lawsuit against Baldoni, It Ends With Us producer Jamey Heath, Wayfarer Studios head Steve Sarowitz, and the men's publicists.

Millie Bobby Brown‘s chic, glamorous look at the after-party of the “Stranger Things” premiere sent the Internet into a frenzy. She rocked a custom Rodarte gown on the red carpet, and later opted for a minimalistic look with a corset top paired with a micro mini skirt.

After going viral for blasting tabloid headlines about her appearance, Millie Bobby Brown reflects on her contentious relationship with the press. 'It is so wrong and it is bullying.'
