My personal Favourites are
The Lord of the Rings Series, Especially the Extended Cut, With the Extras.
The Carry On Series, Especially the Earlier movie's in the series.. While a bit vulger at times, they always make me laugh.
Hatari - Wore out two tapes when I was a kid. but then again, I was crazy about wild animals at that time, living in Tanzania.
Born Free - Again, a movie I used to see monthly, if not weekly. That reminds me, need to find a new DVD of it, as the old tape is quiet worn.
Cheetah - A Really nice story about about a couple of kids who end up adopting a cheetah cub. Need to hunt down a copy, as I haven't seen it in a few years.
The Herbie Series. The original ones, not the Modern remake.
Mary Poppins - And all time classic.
Willy Wonka and the Chocolate Factory - The original, not the horrible Johnny Depp version.
The Lion King - The First part, didn't like the second very much. but did enjoy the spinoff TV series, based on the adventures of Timon and Pumba.
Shrek 1 - Again, Liked the First the best, but the 2nd was ok. The third Jumped the Shark IMHO.
MIB I - Was one of my all time favorites for a while. while the 2nd was good, it didn't match greatness of the 1st.
3 Ninjas - Nice Kids adventure, where 3 kids are trained as ninjas by their grandfather, I believe there were 3 or 4 movie's in the series, but the 1st couple were the best of the bunch.
7 Luck Ninja Kids - I thinks that was the name. Believe was HK film, about 7 kids all with different skills who get together to solve a mystery. Is a cute movie, and if you area kid, even more fun .
The Police Academy Series - If you haven't watched it, its a must. Great comedy, and while a bit dated at times, is a classic in my opinion, even if in many ways they do typify the typical B-movies.
Ninja academy - In the same vein as the Police academy, A great B grade comedy movie, spoofing everthing in site.
The Pink Panther - Peter Sellers at his best.
Down Periscope - Great Comedy. Great for a few laughs.
Under Siege 1 and 2 - two of my favourite action movies. Really enjoyed the fight sequences.
Bloodsport - Probably one of van dams better movies. Just watch it for the fight sequences if nothing else.
Kindergarden Cop - Nice to see Arnie in such a position.
Mrs. Doubtfire - One of Robin Williams Best performances.
Toys - Also one of his better ones. Really liked this movies as it combined my childhood fascination of toys with weapons.
Indiana Jones and the Last Crusade - My Favourite in the whole series.
Lilo and Stich - Great, and love the music. Hawaiian Roller Coster Ride indeed!
The Gods Must be Crazy - Hilarious Series. a must see. Its about what happens when a bushmen village in the Kalahri come into contact with te modern world and the results.
The Rescuers - one of disnys older, less well known movies, but still a great one.
Cirque du Soleil: Journey of Man - while not a movie per se, is still one of favourite DVD's to rewatch, but even better is ...
Cirque du Soleil: Alegrķa - My all time favourite performance. love the music. I do have most of the other DVD's but this is the one I always turn to.
Kill Bill - Have to watch both parts back to back to get the full effect.
Enter The Dragon - My Favourite Bruce Lee Movie. Probably helped start my martial arts movie obsession.
Most of Jackie chans older HK movies. Not so much his newer stuff.
King Kong - The new one, haven't seen the older versions.
The Bridge over the River Kwai
The Great Escape
The Hogfather - This is proably one of the best adaptions of a novel I have ever seen. If you like Terry Pratchett, it is a must see. Even If you don't its worth a look.
Whew! That All That I can think off the top of my head
