I think you have done an awesome job with the JC covers thanks for
posting them. I am a big JC fan myself and have all his films listed on his
official site apart from the unreleased and "The Huadu Chronicles: Blade of the Rose (2004)" which I will get eventually. It's unfortunate that you are
missing the following covers:-

Chinese Zodiac (to be released so don't count) (2012, In production)
Kung Fu Panda 2 (2011)
Looking for Jackie (2009)
Kung Fu Panda (2008)
The Huadu Chronicles: Blade of the Rose (2004)
Enter the Phoenix (Hong Kong: English title) (2004)
An Alan Smithee Film: Burn Hollywood Burn (1997)
Cannonball Run II (1983)
Fearless Hyena II (1980)
Spiritual Kung Fu (1978, also: Karate Ghost Buster)
Magnificent Bodyguards (1978)
Half a Loaf of Kung Fu (1978)
To Kill with Intrigue (1977, also: Jackie Chan Connection)
Killer Meteors (1977, also: Jackie Chan vs. Wang Yu)
New Fist of Fury (1976)
Hand of Death (1976, also: Countdown in Kung Fu)
All in the Family (1975)
Not Scared to Die (1973, also: Eagle's Shadow Fist)
The Heroine (1971, also: Kung Fu Girl)

if it wasn't for the missing above it would have been BRILLIANT!
especially for me :-)
I'm thinking of doing something similar myself for my personal collection and I can imagine how long it takes to make something like that,
never the less you've still done an amazing job, Well done and keep it up!
