Since Art is a musician, was it important to cast someone with musical talent? In this same vein, did Robert play a lot of music on set?
Oliver: Nikki is the most musically untalented person I know - teaching him to (pretend to) play drums was certainly a challenge. Ronny is a musician in his own right and releases albums under the name the rollercoaster project. He wrote all of the music that he plays in the film. Rob can also play - last time I spoke to him he said he was doing some recordings in L.A. - again I think he underplayed how much guitar he could play in his auditions - he said he could only muster a few chords as I recall….
