19 MCU Actors Who Were Also In LOST
16. Rebecca Mader
On Lost: She joined the show during its fourth season as anthropologist Charlotte Lewis, one of the freighter folk who arrived on the island. Though her status as a man cast member came to an end following Charlotte's death early in season five, she returned for two further appearances in the final season.
In the MCU: In a role that's essentially blink or miss it, Mader appeared in 2013's Iron Man 3 as the AIM agent who successfully posed as a Pakistani sweat shop worker in order to disable and retrieve the Iron Patriot armor when Rhodey came calling.
