If you've been in Hollywood this week, you may have noticed things look a bit different as a famous filmmaker transforms the neighborhood into the Tinsel Town of his youth.

Director Quentin Tarantino's currently making his next movie, "Once Upon A Time" With Brad Pitt and Leonardo DiCaprio.

The film is set in 1969 and production crews have been transforming a stretch of Hollywood Boulevard between Cherokee and Las Palmas - meticulously recreating businesses from that groovy chapter of L.A.'s history.

Guest host Alex Cohen hops in the time machine with a couple of Los Angeles historians and the owner of a vintage movie bookshop on Hollywood Blvd to reminisce about late 60s era Hollywood and look at the accuracy of the makeover.
