So he made this movie "The Wrong Move" in 1975 ... and he was 14 years old? This doesn't sound right. If he really did direct a movie when he was 14, how could it be any good?

Perhaps a wee bit of confusion with two "14's" in the mix. Wenders was 30, born 14 August 1945; actress Nastassja Kinski, age 14, born 24 January 1961 ~Wikipedia

Also went on to direct her in "Paris, Texas." But good for him for wanting to correct the past.
I think there were nude scenes in "Pretty Baby" with a very young Brooke Shields. But I guess it's too late for Louis Malle to correct that if he wanted to.

Brooke Christa Shields (born May 31, 1965) is an American actress and current president of the Actors' Equity Association.[2] A child model starting at the age of 11 months,[3] Shields gained widespread notoriety for her leading role in Louis Malle's film Pretty Baby (1978), in which she appeared in nude scenes shot when she was 11 years old. She continued to model into her late teenage years and starred in several dramas in the 1980s, including The Blue Lagoon (1980), and Franco Zeffirelli's Endless Love (1981).

Or so I'm told.

Grotesque theme with a general release.

Stealing Beauty hit me the same way

it seems like she could have done a better job of protecting her when she started acting in films.

This in no way absolves Wenders, Peter Sykes, or Polanski.

I've been a huge Kinski fan for many decades but have never seen this movie. Just as well.
