Sideways (2004)

Continuity mistake: In the scene where Jack and Miles get out of the car at Miles' mother's house, Miles hands the flowers to Jack's right hand. The very next cut shows Jack carrying the flowers in his left hand.

Jack: Are you still seeing that shrink?
Miles Raymond: I saw him on Monday. I spent most of the time helping him with his computer.
Jack: Well, I say, fuck therapy. And what is that stuff you take... Xanax?
Miles Raymond: And Lexapro, yes.
Jack: Well, I say, fuck that too. You need to get your joint worked on, Miles.

Trivia: When Miles is stealing money from his mother he looks at the pictures on her dresser. One of the pictures is of Miles and his Dad. It is actually Miles real dad. Miles is played by Paul Giamatti and his dad is Bart Giamatti former Commissioner of Baseball. That is who is in the picture smiling with Miles.

Question: After Miles accidentally mentioned the rehearsal dinner to Maya, she asked him who's getting married and obviously (though not on camera), he told her Jack, thus starting a big fight with each other. Why did Miles tell her Jack instead of making up a random stranger he could say they knew since already slipping out info about the dinner? She would not have ever known, no fight would have taken place, and Jack would have saved face - literally.
