Among this season's eclectic group is a New Hampshire cop with a hippy past (Besty), a young rocket scientist who claims to work well under stress (John), a former college football coach turned personal chef (Mike) and a man with an insane strategy (Russell H.).
"This group reminds me a little bit of 'Fans vs. Favorites' in terms of there's a sense of fun and [it] actually looks like they'd be fun to hang out with," said "Survivor" host Jeff Probst.

An interesting twist was also revealed. At the start of the game, competing tribes will be asked, without speaking, to immediately pick a chief - someone to make all the decisions for the group.
Despite the picturesque landscape, the castaways will face exposure to elements and wildlife living in the mysterious rainforests that cover rugged volcanic mountain peaks. For 39 days, they will endeavor to outwit, outplay and outlast one another to win the title of Sole Survivor.
The new season premieres Thursday, Sept. 17, at 8 p.m. ET on CBS.
