Lily Tomlin...
... was fantastic in this movie!
Timing the police to see how long it takes for them to arrive to the house: "Two minutes and forty six seconds". The way she walks and opens the door for the CEO, even when she stops people when he is stepping out of the elevator.
Or, when Jethro says he can walk her to the door, she turns around and stops for a couple of seconds before saying: "Well, thank you Jethro".
She's great!
