James Franco pointed out just that when he interviewed the American Horror Story star for Heroine Magazine (via Huffington Post), telling Emma, "So now I'm going to embarrass you."
"No, no, no, what are you going to say?" the 23-year-old actress said in response. "I felt like our kiss was better in the second movie [I Am Michael]," he added. The duo smooched for the first time in their 2013 flick Palo Alto. "Oh my God!," Emma replied before giggling. "You're being such a trouble maker!"
"So either you got better at kissing...," he continued. "Oh my God that's the rudest thing ever!," she replied with a laugh. "[I] was thinking maybe you were just being an amazing actress," he continued. "Maybe I'm a character actress," she replied. "I didn't realize you were playing such close attention on both movies, or maybe I would have done it differently."
The thesp continued to tease his costar, saying, "Which character do you think has kissed more people? The young girl in Palo Alto or the budding young Christian in Michael?"
"I thing you've kissed more than both of them put together," Emma quipped with a laugh. Still, James wasn't done with her just yet. He added that they had "such weird but ultimately such great chemistry," which led Emma to suggest they should play brother and sister in their next film.
"I feel like if we play brother and sister it's going to have to be incestuous because our relationships are always weird," James said as Emma added, "Or maybe we'll just play really normal boyfriend and girlfriend?"
"I don't think it would work," he replied. "I don't think it would work either," she said. Don't forget to check out Emma and James in action when their film I Am Michael hits theaters Jan. 29, and their full interview in Heroine when Issue 2 of the mag hits newsstands Feb. 5.
