The ABC hit has confirmed Samuel L. Jackson as Nick Fury in the May 13 season finale, and "How I Met Your Mother's" Cobie Smulders as Agent Maria Hill on the April 29 episode, according to E! News. Smulders will also be appearing in the season finale. 

Both have previously starred on the show, making brief appearances in the show. 

"S.H.I.E.L.D.'s" most recent episode ties directly with the plot of "Captain America: The Winter Soldier," so it will be very interesting how both Fury and Hill will be drawn into the story lines. 

Stay tuned to "Agents of S.H.I.E.L.D" to see how these two characters will all play out on Tuesdays at 8 p.m. on ABC.
