When the character of Brandy Friday is watching the trailer for Hotel Reverie on YouTube, it mentions 1941 as the year, but both the screen test and the year of the film are shortly listed later on screen (the screen test in the video and the film in the recommended list) as being from 1949.
When Brandy's agent calls from his office, game of Balatro is played on a laptop, where the actor chooses Full House combination, when the proper move is to play a single Six to get a Spectral card. However, there's no right or wrong way to play the game and if he doesn't want to activate that joker that's his decision.
As Brandy sits at the bar after her reveal to Dorothy, you can see the actor holding paper on the right moving as he is trying to freeze/stay still.
