Legends of Tomorrow executive producer Phil Klemmer just confirmed that future versions of Barry Allen and Oliver Queen are locked to appear on the time-traveling, anthology series. Fans who keep up with the news cycle will recall that Oliver Queen actor Stephen Amell hinted earlier this year that such a scene was taking place on LoT as the actor previously stated that he would never wear a goatee as Oliver Queen. However, this is the first confirmation that a future version of Barry Allen will appear. It will certainly be interesting to see how the show decides to make the youthful-looking Grant Gustin appear older.
Legends of Tomorrow will premiere on The CW at 8/7c on January 21.
