Most attendees donned black and the Time's Up pin badge in support of the Time's Up movement.
The Baftas are being hosted this year by British film and TV star Joanna Lumley, who praised the gender equality movement as a continuation of the work of the Suffragettes a century ago. "Sort that out and social problems will get sorted out", he said. "And with it, the determination to eradicate the inequality and abuse of woman the world over". "I also want to say that I appreciate a well-organised act of civil disobedience".
Of course, the Baftas also celebrated the best of film.
Frances McDormand won the best actress award for the film which tells the story of lead character Mildred Hayes as she battles against a revered police chief after months have passed without a culprit in her daughter's murder case.
The Oscars favourite, directed by Martin McDonagh, won in five of the eight categories in which it was nominated.
(Although, oddly, Dunkirk wasn't nominated for best British film and Three Billboards was, ostensibly because McDonagh hails from the United Kingdom, and Three Billboards topped Darkest Hour for that award, too.) In other words, the BAFTAs may have confirmed what we already knew: Three Billboards' most formidable competition for the best picture Oscar is probably Shape of Water (which also has the most Oscar nominations) and Get Out, not another British pick, and it remains anyone's guess as to which of those three will prevail. The ceremony featured a special performance from Cirque du Soleil, which featured two acrobats dressed as character from the film perform a stunning dance. I thank you Sir Winston. Having also won the same award at multiple other ceremonies this awards season, Oldman looks set to finally win his first Oscar. It won Best Foreign Picture and Best Production Design from the Los Angeles Film Critics Association (LAFCA) in December the same year.
It was somewhat more surprising to see Blade Runner 2049 chosen over presumptive frontrunner War for the Planet of the Apes for best visual effects (an Apes film has somehow never won the visual effects Oscar) and Baby Driver chosen over Dunkirk for best film editing. The former has gone primarily unrecognised by other awards.
Ridley Scott, whose films include Blade Runner, Alien, Thelma and Louise and Gladiator, received the academy's highest honour, the BAFTA Fellowship.
"Teaching is the most important of professions".
Dedicating the award to his mother, he said: "I am a product of arts funding within the UK". Gemma Arterton, star of the stage musical Made in Dagenham, concerning the strike at Ford Dagenham in 1968, was accompanied by two of the machinists who took part in that industrial action.
Nearly 200 British female entertainment stars called for an global movement to end sexual misconduct across society in a letter published ahead of the awards.
"As we approach the Baftas - our industry's time for celebration and acknowledgment, we hope we can celebrate this tremendous moment of solidarity and unity across borders by coming together and making this movement worldwide", the letter said.
The open letter from women in entertainment states: "This movement is bigger than just a change in our industry alone".
"We need to examine the kind of womanhood our industry promotes and sells to the world".
The "Time's Up" campaign against sexual misconduct was a recurring theme throughout the evening. "This is your moment too", the letter concluded.
