Barry Allen may be a squeaky clean hero, but Grant Gustin says a few f-bombs were thrown on set. However, apparently the show’s colorful language is limited to the uncut blooper reel. According to, Gustin loves watching the bloopers every year. “I just watched it, like the uncut version, but we have like the f-bomb and all the stuff they’ll cut and it’s like 12-minutes long right now and honestly I watch it at this time of year every year and it just makes you so happy.
