Following the EE British Academy Film Awards’ ceremony on Feb. 16, the night’s winners, losers and a glut of guests were prepped to dine, drink and dance in the depths of the Grosvenor House hotel.

Best film team “12 Years a Slave” were regrouped and reminiscing. Pic’s Michael Fassbender recalled the old set socials as he prepared himself for receipt of a canapé missile: “We went paint balling. I got shot point blank — it looked like I had hickies all over my face.”

Pic’s helmer Steve McQueen had paced himself during the season of celebration, explaining he doesn’t party too hard, claiming, “I’m old, I need my sleep!”

Post-dinner, some guests, perhaps needing to snooze, made a Cinderella-style midnight escape. Most, however, joined a barrage of festivities, splintered across the city.

Harvey Weinstein and pals headed east, as Weinstein hosted his post-dinner bash at the Rosewood hotel in Holborn, joined by the night’s best actress Cate Blanchett, nom Oprah Winfrey and awards’ host, Stephen Fry.

Amy Adams also attended the Weinstein fete. Now on home turf having perfected her “American Hustle” Brit accent, she divulged the location of her English elocution schooling: YouTube, articulating, “I watched YouTube videos of women of that time; Marianne Faithfull and Julie Christie.”

Awards’ opener Tinie Tempah headed east from Grosvenor House, too, with a celebrating “12 Years” producer Brad Pitt and Angelina Jolie in towThe trio ventured to Fitzrovia’s newest hotel, The Edition, for eOne’s night owl after party, where drinks rolled ’til the break of dawn, in brilliant Brit style.
