I want to find a movie I’ve been trying to find since i was a child

This movie had a dragon tattoo that acted as some sort of a key that unlocked something important to the movie plot and that tattoo could change their hosts based on their will I guess. ( it’s not the “girl with dragon tattoo “)

for some reason “samourais” instantly came to mind, but it was a spider marking not a dragon tat

is it the tattooist? The Tattooist (2007) - IMDb
