Shirobako (2014)

There is infrequent mild innuendo, such as a scene where a girl is moaning suggestively while practicing for an audition on a train.

Some references are made to the director's disastrous work on a previous anime entitled "Jiggly Jiggly Heaven." We briefly see a clip from this anime in which bikini-clad breasts are jiggling incredibly unrealistically (played for laughs).

A sleazy man is briefly seen trying to persuade the rest of the anime production team into picking attractive girls as voice actresses, talking affectionately about their "boobs" and using the phrase "dat ass."
