Mind bending visuals and special effects prevail in Marvel's new trailer for Doctor Strange starring Benedict Cumberbatch. The studio premiered the trailer Saturday at San Diego Comic-Con, revealing more plot details about Stephen Strange's transformation into the Sorcerer Supreme. 

The first Doctor Strange trailer, unveiled in April, introduced an erudite and very bald Tilda Swinton as the the Ancient One, who lectures Cumberbatch on his newfound perception and devastating powers. Chiwetel Ejiofor is also in the mix as Baron Mondo. 

But we catch a much more thorough glimpse of Doctor Strange's origin story in the new trailer, as he experiences a near-fatal car accident and travels to Tibet in search of spiritual meaning, etc. Doctor Strange releases on Nov. 4.
