Former Superman Dean Cain & Supergirl Helen Slater Join CBS' SUPERGIRL

The CBS procedural Supergirl has just added a few ex-superheroes to its roster. TV Line reports that Dean Cain, who played Clark Kent/Superman on Lois & Clark: The New Adventures of Superman from 1993 to 1997, and Helen Slater, who played Supergirl in the 1984 film of the same name, have joined the cast in unknown roles.

This casting follows in the footsteps of The CW's The Flash, which hired actors John Wesley Shipp and Amanda Pays from the 1990 Flash TV series, to join the cast of the new series. Fans seem to appreciate these bits of meta-casting, so it makes sense that Supergirl would try to incorporate some members of the Superman universe into their attempt to launch a new show. We know that the crime drama will star Melissa Benoist in the title role, Mehcad Brooks as Jimmy Olsen, Laura Benanti as Kara Zor-El's Kryptonian mother, and Calista Flockhart as Cat Grant, so who does that leave for Cain and Slater? Kara's adoptive parents, perhaps?

But since word just came out that Superman himself would appear in a small role in the series, wouldn't it be ridiculous (and kind of cool) if Cain was suiting up as the Big Blue Boy Scout once again?
