Gaspar Noé‘s film has numerous references to lots of classic films and it will be examined in the future, when a disc/digital edition will be available. Until then, a little preview, a still from film’s press kit in which a poster of Taxi Driver is prominently featured (and also on the right, it looks like that there are smaller posters of Tod Browning’s Freaks).
Martin Scorsese’s Taxi Driver (1976) in Gaspar Noé’s Love (2015).
