Welcome To The Dollhouse: Dawn Weiner has some of the worst parents in the history of film.

Frank Zito's mother in Maniac. In the original it is strongly implied that his mother regularly burnt him with cigarettes, we see the scars in the opening scene on his chest as he examines them in a mirror. There is also a scene in which he burns a little boy mannequin with a cigarette in the same place, while he has an audio flashback of his mother's psychological abuse. There are several audio flashbacks of her locking him in a closet as punishment while he begs her not to. In a scene where he talks to a victim (who he imagines as his mother) he mentions how she brought men back to the house for sex in return for money, and how he had witnessed this as a child. He also mentions how she would go out and leave him on his own. In the remake, there are visual flashbacks of him witnessing his mother having sex with her clients. He was locked in the closet and she knew he could see her having sex, so in the case she intended him to witness it. Another visual flashback is shown of his mother having sex with a client, this time outside (and at night), Frank watches them and is clearly disturbed. She is then verbally abusive to him and shouts at him to wait in the car.

The monstrous Mrs. Bates in Psycho inflicted awful emotional abuse on her son, Norman. First of all, she cut him off from all other society throughout childhood, making him utterly dependent on her. All the while, she tells him that sex is evil and dirty, and that women are whores (except her). She then abandons him at age 12 when she finds a boyfriend. Unable to deal with the loss of his one companion, Norman murders them both. Wracked with guilt afterwards, he develops an identity disorder, occasionally taking on her personality to deal with his guilt and grief. Unfortunately, even the internalised Mrs. Bates is emotionally abusive, and Norman is riddled with anxieties over his sexuality and still smothered by his domineering mother.

Mr. Deeds implies that the father of one of the characters was physically abusive, as Mr Deeds' character lectures the character about swearing in front of the ladies as well as skipping school. Although he does tell the dad about skipping school, he apparently didn't tell the dad about swearing in front of the ladies, to which when he found out from Deeds, he was implied to have beaten the son with a belt. It is done for laughs. With the character being an (adult) football player.
In the movie Natural Born Killers there is a flashback which shows Mickey as a deliveryman who came to the house where Mallory lived with her abusive father, her neglectful mother, and her younger brother Kevin. The flashback is portrayed as an All In The Family or Married... With Children-style sitcom with a canned laughter track, the "audience" laughing hardest when Mallory is subjected to lewd comments, being molested by her father, and threatened with rape. It's implied he's raped her before, when her mother notes that Kevin was only born because her father was drunk and didn't realize he was in his own bedroom, and not Mallory's.
This is a plot point in Chinatown, and is the source of one of Film Noir's most shockingreveals. To make a long story short, Noah Cross raped Mrs. Mulwray and she had a daughter by him. Mulwray's protectiveness toward her drives a good amount of the plot.

Eastern Promises. Semyon is physically and verbally abusive well into Kirill's adulthood. It may have gotten worse now that Kirill's a grown man, and is also, at least implicitly, because Kirill is likely gay. It comes across as worse in contrast to how Semyon treats the little girls in their family, which seems genuinely avuncular. Well, maybe not all the little girls in his family — Semyon also orders Kirill to murder one of his illegitimate children, who would be Kirill's own infant half-sister.

John Schneider's character Jacob, from October Baby, is a rare unintentional example of this trope. He lies to his adopted daughter, uses the borderline-suicidal passages in her diary as a pretext for further hospitalization, violates the Hippocratic Oath, pushes her out of relationship with her best friend, and threatens to pull her out of college. All for her own good, mind you.
Nathan Grantham in Creepshow, as well as the father of the boy who's reading the comic in the framing story.
The dinner table scene in After Earth goes a bit too far with Cypher's aloofness to his son, making him seem like this instead. Especially when you learn the reason for it is that he resents Kitai leaving his sister to be killed by an ursa, when he would have undoubtedly just been killed himself if he'd stayed.
"You know, I've often wondered why it is we have children in the first place. And the conclusion I've come to is... At some point in our lives we realize things are screwed up beyond repair. So we decide to start again. Wipe the slate clean. Start fresh. And then we have children. Little carbon copies we can turn to and say, "You will do what I could not. You will succeed where I have failed." Because we want someone to get it right this time. But not me... Personally speaking, I can't wait to watch life tear you apart."

Trust me, you do NOT want to have a mother in Carved: The Slit-Mouthed Woman. Every child that does (except for Natsuki) was physically abused by their mothers. note Especially Mika, Dear God...
Nina's mother in Black Swan is shown to be overbearing and emotionally crippling; she still lives with her twenty-eight year old daughter, constantly keeps tabs on Nina's career (by phoning in to the people at the ballet company), projects her own regrets and failures on her - at one point implying that Nina was the reason she had to give up on her dreams... to Nina's face to less, and is presented to the audience as a barrier between Nina and her sexuality, let alone adulthood in general. How much of this is the real her, and how much is a result of Nina's slowly slipping grip on reality is anyone's guess.
K. Roth's mother in The Living Wake is of the emotionally abusive variety. Coldly blames his father's disappearance on him (as in, tells him to his face that it was his fault. And his father disappeared when he was five), and refuses to believe him when he tells her that he only has one day left to live, and would like her to come to his funeral, which he'll be leading later that day. Once he actually does die, she does show a bit of remorse, but not nearly enough.
