'Guardians of the Galaxy Vol. 3' production is on hold.



The movie was set to go into pre-production soon with principal photography slated to begin this winter, but according to The Hollywood Reporter, crew members preparing for pre-production have been let go and told they can find other work.



This comes after director James Gunn was sacked by Disney in light of a series of controversial tweets.



Alan Horn, Walt Disney Studios chairman, previously issued a statement in which he detailed the reasons for sacking the director.



He said: "The offensive attitudes and statements discovered on James' Twitter feed are indefensible and inconsistent with our studio's values, and we have severed our business relationship with him."
