I think you're talking about the movie Matilda.
Thank you, but that's not it. I remember details, that midget, or at least small man, had a beard, and had some generator of objects. When fight began he and kids tried to create weapon, but created just golf club or something not suitable. I clearly remember how woman catched whip and spinning, makes girl fly in air. I think, it was part of some series for children.
I remember a last part of episode in a show, aired in mid-late 90's Russia. I think, there was a group of children, or at least young teenagers, who met woman and midget. They fight different enemies in some сhallenge, and i clearly remeber some amazon-like girl with whip, who attacked the woman. Woman catched whip and started to spinning in place so fast that makes girl fly in the air, then throw her in wall, and girl disappeared. I was only like 7-8 years old, so i don't remember any better.
