Looking For Movie Title

Looking for Movie Title

I made another post previously, but I think I got some of my facts wrong what I know for certain about the movie I’m looking for is that my sister and I got it for Christmas in the early 2000s there was a boy and his sister probably age 8. There is a dog. At least one of the movies the kids are in a haunted mansion. I think the most identifiable thing is that the DVDs came in a box set each DVD had a different case and the cases were really skinny so they all fit in the box set.

1. Movie from the early 2000s
2. 8 year old boy and his sister
3. Dog (possibly a beagle)
4. At least 1 movie in a haunted mansion
5. Thin DVD box set
