Donovan Patton is an American actor and television host. Patton graduated from the Interlochen Arts Academy and acted in Shakespeare plays such as Much Ado About Nothing and Romeo and Juliet before replacing Steve Burns as the host of Nickelodeon's long-running children's television program, Blue's Clues in 2002. Series co-creator Angela Santomero stated that Patton brought Joe, his character, closer to the preschool viewer, as Joe was more willing to "jump into a problem rather than figuring it out first like Steve". After Blue's Clues ended in 2006, Patton then voiced Bot on Nickelodeon's Team Umizoomi (2010–2015) and currently voices CatRat on the Netflix original DreamWorks series Gabby's Dollhouse. Although most of his career has been in children's television programs, Patton has also appeared in independent films, such as Black Wine (2005), Awake (2013), Lies I Told My Little Sister (2014), The Broken Ones (2017), The Murder (2019), The Anniversary (2019), Psycho Escort (2020), and DieRy (2020), and in television shows, such as Blue Bloods (2011), Nurse Jackie (2011) and Damages (2012). He also appeared in video games, such as Grand Theft Auto V (2013), Lego Jurassic World (2015), Star Wars: The Old Republic – Knights of the Fallen Empire (2015), Halo 5: Guardians (2015), Horizon: Zero Dawn (2017), and God of War (2018).
