S.H.I.E.L.D. (or Strategic Hazard Intervention Espionage Logistics Directorate) is the agency that put together The Avengers. What makes this TV series exciting is that the series plays out in the same Marvel universe that we’ve experienced in the movies. The series will also be directed by Josh Whedon, he also directed The Avengers. Continuity will therefore be shared between Marvel movies and the Agents of SHIELD TV series.
This will not only be a great addition to the Marvel franchise but it will also be a great addition to the entertainment that is viewed by Marvel fans worldwide.
