T.J. Miller—maybe the most recognizable voice in comedy these days—can spitball one-liners like he was raised on a compound by Groucho Marx, Woody Allen, and Rodney Dangerfield. His style is all millennial though, and he’s like the friend you invite to every party and would be top pick if trading insults were a sport. So having him in Deadpool, the eponymous film about the “Merc with the Mouth” (who might as well count wit as a superpower) is a blessing. The trailers have dropped a lot of good lines, but it turns out when Miller and co-star Ryan Reynolds got going, it was hard to turn it off and some comebacks were too dirty harsh to include in the R-rated flick. As Miller puts it, “[Reynolds] can improvise with the best of them, and I am the best of them.”
