Atticus Shaffer (born June 19, 1998) is an American actor known for playing Brick Heck on the ABC sitcom The Middle (2009–2018), as well as for voicing Edgar in the film Frankenweenie (2012) and Ono on the Disney Junior series The Lion Guard (2016–2019), and for his brief appearance in Hancock (2008).

In a Wired magazine interview published in January 2013, Shaffer said his role as Brick was similar to his own life, as he is also a "big reader" and "nerd[s] out over the weirdest stuff".

[3] Brick's characterization, including his idiosyncratic palilalian repetition of words and phrases at the end of sentences, is based on The Middle co-creator Eileen Heisler's son, Justin.

[4][5] Shaffer has type four osteogenesis imperfecta,[6][7][8] a condition involving a defect in collagen that causes fragile bones and short stature.

[9][12] Shaffer has official YouTube and Twitch video gaming pages, titled "AtticusShafferVlog", the latter of which he announced in December 2019.
