Another view from the film. Thanks to Chris Bungo for the screenshots. See his great eighteen minute "then and now" comparison of shooting locations for several films in the "Taxi Boys" series on YouTube.
Many Culver City locations were used in addition to the Westwood shots. The Fox Westwood Theatre shots from "Thundering Taxis" start at 8:32. Shots from "What Price Taxi," another film in the series, start at 12:47.
Chris has done another seven minute video just devoted to "Thundering Taxi" locations. It's also on YouTube.
For more about the theatre, see our page on the Fox Westwood Village. The theatre opened in 1931 and still remains a major first-run venue. It's now known as the Regency Village Theatre.
