Now a cult classic, this quintessential kids' Halloween movie has it all; a coven being raised from the dead in Salem on All Hallow's Eve, a talking cat, a wholesome teenage romance, oblivious adults and, of course, a group of plucky kids saving the day. With some scary themes and fight scenes, it's probably best suited to 8 and over.
Coraline (2009) Whilst not set during Halloween, Coraline definitely delivers the creepy.
After moving into a new house with parents who seem too busy for her, Coraline discovers an enchanted doll who transports her to an alternate world and a new mother who adores her. However, all is not as it seems and Coraline soon learns a hard lesson in being grateful for what you have. With heavy-duty themes including death and parental loss/abandonment this really isn't a film for kids under 10, although my 7-year-old absolutely adores it and has watched it more times than I can count.
And because this list could easily turn into "Every Animated Tim Burton Movie Ever", similar recommendations go to The Nightmare Before Christmas, a musical where the King of Halloween falls in love with Christmas; The Corpse Bride, about a young man who accidentally marries a long-dead bride; and Frankenweenie, the story of a boy who brings his dog back from the dead. Coraline gets the bonus points for having a young girl as the protagonist.
Double, Double, Toil and Trouble (1993)
This fun, Halloween-themed romp stars the Olsen twins at their 7-year-old peak cuteness, playing twin sisters who rescue their great-aunt from her evil twin sister using their ingenuity, loyalty and love for each other. This is a fun movie that will be fine for kids of all ages, although older kids might get a bit bored, and is a great example of little girls as the heroes who save the day.
Hotel Transylvania 1&2 (2012, 2015) If you're looking for movie marathon this duo will fit the bill nicely.
Hotel Transylvania introduces us to Dracula; widow, father and hotelier offering sanctuary to monsters looking for a holiday where they will be safe from the dangers presented by humans. Dracula is trying to discourage his daughter, Mabel, from going out into the world where he is certain she will meet with harm, but during preparations for Mabel's 118th birthday party, Dracula accidentally allows a human, Johnny, into the hotel and Johnny and Mabel fall in love. The sequel picks up after Johnny and Mabel's marriage and the birth of their first child and sees the family trying to discover if the baby is monster or human. Both movies are good fun for the whole family, including adults but fortunately without some of the more questionable "for adults" jokes of other animated films.
Spooky Buddies (2011) - a Halloween themed adventure from the successful and fun all-ages franchise featuring talking dogs.
The Witches (1990) - an occasionally scary adaption of the Roald Dahl book, suitable for older children.
Pooh's Heffalump Halloween Movie (2005) - kind of a sequel to 1996's Boo to You Too! Winnie the Pooh, the Hundred Acre Wood Gang go on a monster hunting adventure. This is a great one for the tiny tots who might not be able to join in some of the big kids' activities.
It's the Great Pumpkin, Charlie Brown (1966) - at 25 minutes not really a movie, but who doesn't love the Peanuts Gang?
