As noted by 9to5Google, The process starts with telling Assistant that you want seats for a certain movie or searching for showtimes using the Google app. Once a movie time is selected, just hit one of the “Buy tickets” buttons that appear next to each ticket provider.
Once the Assistant panel pops up and the theater’s website loads in the background, Duplex takes over the leg work, asking how many tickets you would like and confirming your details. The service uses pre-filled personal information, such as payment details, where needed, which are saved in Chrome.
