Andrea Castellan, who uses the pseudonym Casty, is an Italian comic artist and scriptwriter. He began writing scripts for Silver's Cattivik comics in 1994, and started doing art on them in 1999. In that same year, he began working on Silver's other comic series, Lupo Alberto. In 2007 he was involved in the Cattivik television series for Mediaset. Casty started writing scripts for Topolino (Mickey Mouse) in 2003. He does art for the Italian Mickey Mouse stories as well, in a style closer to classic artists like Scarpa and Gottfredson, instead of the more regular Cavazzano-influenced Italian style.
