Despite a less than stellar performance at the box office, Warner Bros. is planning a sequel to Ryan Reynolds' superhero pic Green Lantern.

Warner Bros. still believes in the franchise, even if the studio is "somewhat disappointed" with Green Lantern's result.

Over the weekend, Green Lantern fell a steep 66% at the domestic box office, grossing $18.4 million for a cumulative of $89.3 million.

Green Lantern cost $200 million to produce, which doesn't include the sizable marketing costs. Rival studios say Green Lantern's marketing budget was one of the most expensive on record.

No production date has been set for Green Lantern 2.
