Sean Maher
With his dark Irish good looks and an engaging screen presence, Sean Maher rose through the ranks of several short-lived television series, paying his dues before finding a role that would earn him a devoted fan following--ironically, in failed Joss Whedon sci-fi series "Firefly" (2002) which was revived as the feature film "Serentity" (2005), in which he played the straight-laced physcian and devoted brother, Dr. Simon Tam.
