Check out the upcoming line of Hot Toys figures from Star Wars: The Force Awakens (which was great, by the way). They stand around 12 inches / 30 cm tall, fully articulated and with a huge amount of interchangeable accessories, weapons and details. Not to count the VERY accurate faces. Darn, I sometimes thought I was looking at screenshots from the movie. Good job, Hot Toys!
