According to 'Entertainment Weekly,'Duhamel will appear in an episode in August, and there's a chance that he could even appear in a second episode before the veteran soap bows out in September.
Leo died (or did he?) back in 2003 trying to save Greenlee (Rebecca Budig) in a waterfall accident. However, death -- as we all know -- is no impediment to soap opera comebacks and as Leo's body was never found, we'll now get to find out what he's been up to all these years.
Duhamel won four Daytime Emmy nominations for Outstanding Supporting Actor in 'AMC,' picking up the award in 2002. By returning to the show that made him famous he's following in the footsteps of other illustrious soap veterans like James Franco and Julianne Moore.
Franco's stopped by 'General Hospital' several times, playing the dangerous performance artiste known as "Franco." Oscar winner Moore got her start on 'As The World Turns' in the 1980s and revisited the soap before it went off the air in 2010, playing the dual role that won her a Daytime Emmy in 1988 -- half-sisters Frannie and Sabrina.
Maybe now that 'AMC' producers have Duhamel onboard they'll be able to lure back other alumni such as Sarah-Michelle Gellar and Christian Slater for a farewell before the lights go dark in Pine Valley.
