The Spanish drama León y Olvido (2004) stars Guillem Jiménez and Marta Larralde as autistic León and his sister Olvido, a seamstress in a sweatshop who has to take care of her brother. With no one else around, the siblings’ very close relationship borders on being a little too close. Luckily, what is forbidden to some will be forgiven by you, when Marta strips down to join her brother in the tub. The sweetest taboo!
