Stephen Amell this week laid eyes on the script for the first episode of Arrow Season 5, and he liked what he saw.

The superhero series’ star shared in a recent Facebook Live chat that based on reading said script and then chatting with fight coordinator James Bamford, who is directing the new season’s first two episodes, the premiere “has the opportunity for us to have the most vicious, violent one-shot in the history of network television” — meaning a long, continuous take with no cuts (a la Agents of S.H.I.E.L.D.‘s late-season Daisy fight scene, or, in non-network examples, Banshee‘s infamous Nola vs. Burton car fight, or either of Daredevil‘s epic oners over on Netflix).

“If [the premiere] is any indication, Arrow is going to be f–king mean this year,” he added, “and that’s really exciting.” (Amell later made clear, in response to a commenter’s question, that the tone is “not ‘evil,’ just meaner.”)

Amell also teased a “slightly modified version” of the Arrow costume, plus an appearance by “someone that we haven’t seen in two full seasons. So there’s that.” (Before you blurt out, “Sla-a-a-a-ade!!!,” remember that he popped up midway through Season 3.)

Fielding a flurry of other questions, Amell had “no comment” on any Legends of Tomorrow characters appearing in Arrow‘s premiere (which he summed up with the word “legacy”); shared his enthusiasm for The Flash‘s Season 3 premiere title, then said the “Flashpoint” storyline “certainly could” affect Arrow; and when asked, “What about Olicity?,” he playfully hedged, “What about it…?”

Arrow Season 5 premieres Wednesday, Oct. 5 at 8/7c, now leading into the new series Frequency.
