When Oscar sits next to Bosie at the Royal Cafe he gathers his coat around himself twice in successive shots.
After the Marquis of Queensberry left Wilde's home, Wilde (seated) embraced his wife. In one shot his left hand (on her arm) was level with his chin. Then on a change of camera, it was level with his eyes.
The Marquis of Queensberry entered Wilde's study and removed the glove from his right hand then crossed the room. Next, he took the glove from his left hand whilst wearing a glove on the right hand.
After the Marquis of Queensberry left Wilde's home, Wilde leaned forward to kiss his wife and tilted his head to his left. On a change of camera, he withdrew from the kiss. His head was tilted to his right.
After his son's funeral, the Marquis of Queensberry arrived back at his house. All shadows were cast away from the house. after a change of camera, the Marquis walked from the carriage to the house. His shadow was towards the house.
Queensberry leaves Wilde a card accusing him of "posing as a sodomite". The real Queensberry misspelled the word as "somdomite"; presumably this was changed for clarity's sake.
Wilde's friend Robbie Ross is shown as being ignorant of Wilde's homosexuality, asking him to deny rumours of it. In fact Ross was gay and probably Wilde's first male lover.
The card that Queensberry actually said Oscar Wilde posing sodomite and not posing as a sodomite whilst one doesn't actually know why Queensberry misspelled the word sodomite by adding an extra M( possibly inner anger at Wilde,s affair with Queensberry's son made him lose concentration), but it is clear that Wilde was being accused of being gay and not posing as a gay man.
Oscar tells Constance and Ada that "The curtain fell on the third act of The Importance of Being Earnest as the doorbell rang." At that stage the play still had four acts.
Wilde walked on the beach then returned to his holiday accommodation. A bright light was reflected on a black (stable?) door and Wilde's shadow was wider than darker than expected. Evidence of artificial lighting.
After a walk on the beach, Wilde entered the home of Mrs. Birches(?). They each cast two shadows on the wall of the stairs.
When Bosie orders champagne in the Café Royal the waiter pops the cork at the table. Oscar, and his circle, would have considered this outside the bounds of etiquette. Bottles were always opened out of earshot of the guests.
