I've always found it interesting to see which child actors are picked to play the roles of film and TV stars during flashback scenes, and the 'Kid Casting' Tumblr proves I'm not the only one with this insatiable curiosity. The blog is dedicated to collecting screenshots from movies and TV shows, showing both the original actor and the lucky kid in the younger role.

From episodes of 30 Rock that show Tina Fey as a young, awkward girl, to scarier comparisons like that of Angelina Jolie's character in 'Salt,' the blog acts as a reference guide to all your fave child actor pairings. One of my personal favorites is the Larry David young actor casting for 'Curb Your Enthusiasm,' which shows the star as a lanky, curly haired ginger.

Check out the 'Kid Casting' Tumblr for a laugh, and pick out your favorite pairs.
