There's a new trailer for Daniel Radcliffe and Zoe Kazan's new flick, What If, and we're getting major When Harry Met Sally a good way. A Millennial version of the Rob Reiner classic could be completely awful but watching Radcliffe play the cute, guileless Wallace and Kazan as his star-crossed love interest, Chantry, we can't help but be charmed. Rounding out the cast are Adam Driver -- who plays a very Adam Sackler-esque character (or so it seems) -- and Rafe Spall, who play Chantry's cousin and boyfriend, respectively. Peep the trailer, above.

What If opens on August 1.
