WOW....I just saw on the website that they are starting to cast for TBL 5! Kinda sounds like they maybe be casting with a different show format. They are looking for teams of 2 (twins, co-workers, friends, family members etc.) I didn't make it on TBL 4...maybe I will on TBL 5! They say to download the application, but when I went to look at it...it was linked to the wrong show. They also, will start doing live casting calls in August.
Keep watching the TBL website for more details.
