10 Really Scary Movie Moms

On Mother's Day, your mom deserves all the love and flowers you can give. But there are some mothers who make their offspring run away screaming -- if not worse. Here are 10 movie moms that won't be getting any "You're the best!" greeting cards. 

Grendel's Mom (Angelina Jolie) in 'Beowulf' (2007)

Motion capture turns Angelina Jolie into a gold-skinned, shape-changing demon mom, whose son has a face only a mother could love. When her boy is killed, she sets out on a vendetta that is (literally) the stuff of legend. 

Mrs. Focker (Barbra Streisand) in 'Meet the Fockers' (2004)

Things go to a whole new level when Mom's an outspoken, hippie-dippy sex therapist to Floridian oldsters on "Focker Isle." She also embarrasses son Ben Stiller with fart jokes. 

Petunia (Fiona Shaw) in 'Harry Potter and the Chamber of Secrets' (2002)

She's technically Harry's aunt, but Petunia becomes his guardian after his parents are killed. It's not very nice to make your dead sister's only son sleep in a tiny cupboard under the stairs while spoiling your own son rotten.

Margaret White (Julianne Moore) in 'Carrie' (2013)

Carrie's overprotective and overly religious mother uses crazy means to raise her child. She gets what she deserves in the end in both this remake and the Brian De Palma original. 

Pamela Voorhees (Betsy Palmer) in 'Friday the 13th' (1980)

The only thing worse than her hockey mask-wearing, teen-slaying son? His deranged mother. 

Norma Bates in 'Psycho' (1960)

Norman Bates loved his overbearing ma so much, he went more than a little mad -- wearing her clothes and going all stab-happy on people in showers. 

Joan Crawford (Faye Dunaway) in 'Mommie Dearest' (1981)

She puts on a perfect face for the rest of the world, but behind the scenes, she screams "No more wire hangers!" while physically and verbally abusing her adopted brood. She's the worst. 

Erica Sayers (Barbara Hershey) in 'Black Swan' (2010)

Creepy is an understatement for this overprotective mom who likes to watch her ballerina daughter "sleep."

Grace Stewart (Nicole Kidman) in 'The Others' (2001)

While her house is seemingly "haunted" by an elderly spirit in a while veil, the real horror is in the truth that Grace can't accept. And it's not for the faint of heart. 

Mama in 'Mama' (2013)

We saved the best of the worst for last. For nothing is scarier than whatever hell rock this demon-spirit crawled out from under.
