WMG / Annie (1982)

Miss Hannigan is Annie's bio-mom.

True, she hates Annie and obviously thinks of her as a burden, but she seems to focus on her the most out of all the other orphans. Also, they're the only two in the whole orphanage who have curly red hair. Added to that, Miss Hannigan is a total jerk, but she still won't let Rooster kill Annie in the end. Finally, you'd think she'd want to get rid of a child who'd caused her so much trouble, but she protests when Grace wants to take Annie to the Warbucks mansion.
