If it were up to me... I'd do the following: Daylen Amell - Mage Warden with Arcane Warrior specialty. His favourite weapon is a Greatsword and wear Heavy Warden armor (DA2 style) for the first half of the film. Then switch to the Massive Warden commander armor (DA2 Legacy style) right on the Final Battle. He will be using both physical swordplay slashes combined with explosive spells that protects his companions at the same time. Meeting his cousin Hawke in Lothering (male mage/apostate).Siding with King Bhelen, and preserving Anvil of the Void.Curing the Werewolves of the Brecillian Forest.Siding with the Mages.Saving Arl Eamon as well as his wife and connor survived.Landsmeet won closely with 50:50 ratio but up to one noble which sides with the grey wardens for dramatic purposes.Undertake the secret companion to the joining, and Alistair leaves the party but his hardened personality promised to be King and marry anora.Warden romances both Morrigan and Leliana but choose a hardened Leliana. She then agrees about the ritual that need to be done and the Warden do the ritual with Morrigan.In the final battle however, where the Warden was knocked down and almost killed by a Hurlock General, Alistair swoops in to save the day (despite his claims that swooping is bad). In the end, there's three grey wardens fighting side by side in Denerim. So there's Warden, Secret Companion, Alistair, Morrigan, and Leliana on top of Fort Drakon.In the end, The warden slays the Archdemon with a flying greatsword thrust (he's a mage so he can jump unnaturally very high) to the neck, and additionally he shoots a blast of mana from his body through the sword and explodes in the Archdemon's neck blowing its head off with an epic explosion. Everyone else was protected by the explosion from his magic. You can see the essence of the Archdemon flying and going through Morrigan's stomach but didn't come out, and Morrigan turns to an eagle and flies away. The Warden walks out of the burning Archdemon unscathed.The boon chosen was to gain Loghain's land and the Amell warden becomes the new Teyrn of Gwaren. That means there are two Amells noble houses exist. One in Gwaren in Ferelden where the Warden is, and the other is in Kirkwall (or whatever's left of the noble house there)The movie ends with Alistair's coronation and marriage to Anora, and the Hero of Ferelden is hailed through a massive celebration through the streets of Denerim and then credits roll.Post-credits scene plays with "5 months earlier" as Hawke is running away from the Darkspawn overrunning Lothering with his family. He meets with Aveline and fights their way through until a dragon appears and as it shapeshift to a familiar form. Flemeth standing before them saying "Well well, what have we here?" (camera only shows her back starting from her legs and move up to her DA2 designed head. As for the cast, I agree with some of the choices here: The Warden (Daylen Amell) = Chris Hemsworth... (I'm an actor too, so if I'm cast as the Warden is definitely an Honor. Hahahaahah)Alistair = Ryan Reynolds or Scott SpeedmanMorrigan = Eva GreenLeliana = Kate BackinsaleWynne = Helen MirrenZevran = Orlando BloomOghren = John Rhys-DaviesSten = Jason Momoa with prosthetic make up. (make him look like DA2 Hornless Qunari)Shale = CGI with the original voice actor.King Cailan = Jonathan Rhys Meyers or Jake Gyllenhall (if Alistair were Scott Speedman)Arl Rendon Howe = Tim CurryDuncan = Sean Bean or Liam Neeson.First Enchanter Irving = Ian McKellenAnora = Gwyneth PaltrowLoghain = Craig Parker (Darken Rahl from Legend of the Seeker)Hawke = Viggo Mortensen
