In honor of Marvel Comics 75th Anniversary ABC will air a special titled “Marvel 75 Years: From Pulp to Pop!” on Tuesday, November 4 at 9 pm ET
The special will cover Marvel’s history from 1939 to the present, and preview what’s to come in Marvel’s future. It will be hosted by Emily VanCamp—Agent 13/Sharon from Captain America: The Winter Soldier.
This of course means that Agents of S.H.I.E.L.D. will not be airing that week but should resume the following week.
