The film marks the acting reunion of Adam Goldberg and Matthew McConaughey who had last appeared together 10 years earlier in the iconic Dazed and Confused (1993).
After Ben tells Andie he wants to go to couples therapy, she walks away down the street and waves back at him. When she's walking toward the camera, she waves with her right arm while holding the plant with her left. When the shot changes and she's walking away from the camera, she's waving with her left arm.
Just before Andie surprises Ben at work with Krull, Tony hands Ben a mug and he begins to sip from it. Ben has a black mug and Tony has a white one. In a subsequent shot they've switched mugs - Ben is now holding a white one and Tony has the black one.
