O - yes oil slick
R - recitalist
U - urinal
Y - Yokohama

[Lie-in King]

O - Yes - Oil slick (film, noir) - 'oil' (work of art) + 'slick' (polished but superficial)

Recitalist - anag 'realistic' + '(stun)t' (finale)
Urinal - 'Ural' (river, banks; contains) 'in'

Y - Yes - Yokohama - anag 'okay' (round) 'o' (duck; nil) + 'ham'

[Toorak]

Oil - work of art
Slick - polished
Oil slick is a black film
