The Flash: Set Photos Spy Iron Man 3's William Sadler

William Sadler, who played the President in Iron Man 3 and The Grim Reaper in Bill and Ted's Bogus Journey, will apparently appear in the upcoming second episode of The CW's The Flash.

That revelation comes courtesy of a number of fans submitting set photos to Flash Fans, where they've started to make their way out to the wider Internet via social media. 

Muchasa Armstrong, who had minor roles in Arrow and The Tomorrow People, also appears in the photos.

Sadler would be age-appropriate to play The Mist, an aging supervillain whose daughter would eventually take over for him following his death in James Robinson's Starman series -- assuming that's the rough storyline they hope to use for the character, who was teased yesterday in a report on the episode.

Sadler isn't the only character actor to move back and forth freely between Marvel and DC -- especially where TV and direct-to-video is involved.
