Actor Clark Gregg as Agent Coulson


Official MCU Timeline Answers An Agents Of S.H.I.E.L.D. Question
"Agents of SHIELD" never quite felt like it had a place in the Marvel Cinematic Universe, and Marvel Studios has never officially confirmed or denied its canon up until now.
Phil Coulson shows up only a few times in the index for "Marvel Studios' The Marvel Cinematic Universe: An Official Timeline" despite his many adventures on the show.
There’s also zero information on Melinda May, Daisy Johnson, Life-Model Decoys, Ghost Rider, or the Terrigen Mist, which all played significant roles in "Agents of SHIELD."
Even if this series did begin in the MCU, the book detailing all of the cinematic universe’s events unfortunately solidifies the series' non-canon status within the MCU timeline.
