Jordan Moreau Paramount and eOne are launching their new fantasy film “Dungeons and Dragons: Honor Among Thieves” this weekend, and the adaptation of the popular role-playing game picked up $5.6 million in previews at the domestic box office. It opens in 3,855 theaters on Friday. After rolling for initiative, it will prepare for combat against “John Wick: Chapter 4,” last weekend’s box office champion — and it’ll be a close battle. Directed by Jonathan Goldstein and John Francis Daley, “Dungeons and Dragons” is hoping to conjure up $30 million to $40 million in its opening weekend, and Keanu Reeves’ “John Wick 4” is muscling its way to around $36 million in its sophomore outing.
