Watch the "Harry Potter" trio's first screen test

(CBS) Earlier this week, we got a sneak peek at a new clip from "Harry Potter and the Deathly Hallows: Part 2." Now, as the "Potter" franchise's ending approaches, fans are getting a look back at the very beginning.

Warner Bros. released Daniel Radcliffe, Emma Watson and Rupert Grint's first screen test together, reminding those who have followed the series throughout just how much the trio has grown up.

Pictures: "Deathly Hallows: Part 1" premiere

The clip, which hit the web on Wednesday, shows the three actors reciting some lines from the first film, "Harry Potter and the Sorcerer's Stone." It then cuts into clips from subsequent films and the "Deathly Hallows" trailer that everyone saw Sunday night at the MTV Movie Awards.

Watch the video below, but be warned: extreme cuteness (and tiny actors!) abound.
