In the Oxford Dictionary of English 3rd, it says:
It girl

Origin
Coined by the American screenwriter Elinor Glyn (1864–1943) with reference to the American actress and sex symbol Clara Bow, who made her name in such films as 'It' (1927). The current use dates from the 1960s.

'It' is only one film, so why does it use 'such films' instead of 'such a film'?
Would you be so kind as to help me?
Thanks!
