The Avengers star was in town to attend the Comicpalooza convention, and when he returned to the city's Regency Hotel and headed to the bar, he realised he was in the midst of a wedding party.

Pictures show Renner chatting to guests, but the actor tells he ended up leaving the building because he did not want to upstage the bride and groom, adding, "I did enjoy conversations with many of the guests for about 15 minutes and went off to enjoy the sights of Houston for the night."
