He came to greater attention in 2006, when he played as Dwayne, a voluntarily mute teenager as part of an ensemble in the comedic drama "Little Miss Sunshine", which received critical acclaim and collective awards for its cast. He also had a supporting role in the 2006 film "Fast Food Nation", based on the nonfiction book by Eric Schlosser. Dano had a dual role for the 2007 period film "There Will Be Blood", which earned him positive reviews and a BAFTA nomination for Best Supporting Actor. "Texas Monthly" said that his performance was "so electric that the movie sags whenever he's not around." Peter Travers remarked "All praise to the baby-faced Dano...for bringing sly cunning and unexpected ferocity to Plainview's most formidable opponent." "Rolling Stone" magazine included Dano in its Hot List for 2007, calling his performance style "Daniel Day-Lewis + Billy Crudup × Johnny Depp."
