Inside sources claim, the producers are having quiet discussions with the stars about the big-time move. This would lead to an "official" forming of the Justice League/Super Friends on the show. Fans would finally see: Clark (Tom Welling) eventual flying, getting/wearing his Super-suit, and officially accepting his Kryptonian heritage and leaving behind the last of his flawed humanity. Then, see Welling satirizing that behavior to his own amusements- in hip geek version of Kent, Reeves-style.
The producers feel it would be a perfect time, since Elizabeth is damaged goods at the moment and is desperate for work. Kilmer has finally reached a point in his career, when he is affordable and willing to work in TV (voicing the new KITT in a failed Knight Rider reboot and a failed TV movie that aired on NBC, that should remain nameless.)
Also, with the show going into its ninth and last season, the show could use the two actors- to push the ratings up. Since, this would be Kilmer's most likely final time- playing the role and the prospect of Shannon fighting and emoting half-naked, could give her just the career boost- she needs.
Finally, if the network succeeds in this move- would give a product placement plug- to an upcoming arcade game, about the Justice League to debut in the fall.
