Kelsey Grammer is joining the CW's Arrow for a very unique 150th episode on February 4, according to Entertainment Weekly. The episode, titled "Emerald Archer," will be a faux documentary about the Hood (how Stephen Amell's Green Arrow is referred to by the public in the show) and the rise of his fellow vigilantes. Grammer will serve as a narrator for this unique presentation.
"The 150th episode of Arrow showcases a documentary entitled 'The Hood and the rise of vigilantism’ starring Oliver Queen (Stephen Amell), Felicity Smoak (Emily Bett Rickards), and the rest of Team Arrow," reads CW's description for the episode. "As a camera crew follows Oliver and team around to talk about their past as vigilantes and what the Green Arrow means to Star City, Oliver must also deal with William’s (guest star Jack Moore) return from boarding school as well as a new threat to the city.
"The episode will feature 'documentary footage' captured by the BTS crew and interviews from those who have worked alongside the Green Arrow. The documentary is narrated by Kelsey Grammer."
Glen Winter is returning to direct the episode, which was written by Marc Guggenheim and Emilio Ortega Aldrich.
It isn't clear if Kelsey Grammer is playing himself or a character; the veteran actor was previously reported to be in talks to play the Chief on DC Universe's Doom Patrol, however Timothy Dalton ended up cast in the role. Grammer previously played the Beast in 20th Century Fox's X-Men movies.
