Henry Cavill girlfriend Gina Carano's return to the MMA arena is not likely to happen soon. According to Fox Sports, Carano's agent, Scott Karp, told MMA Fighting's Ariel Helwani that she will be filming two movies before the end of the year.

Reportedly, the former "Strikeforce" champ will be shooting "Bus 657," which stars Robert De Niro, in October. WWE star Dave Bautista, another former MMA fighter will join her in the said movie. Carano also is filming a second movie in December.

Meanwhile, UFC Pres. Dana White expressed his sentiments in dealing with the former athlete. According to online site MMA Fighting, White referred to Carano as "the hardest human being we've ever dealt with" as he spoke to media in Las Vegas on Thursday.

"I didn't see it coming," White said as reported by Fox Sports. "I don't know, we'll see how these things play out. Just incredibly difficult. We've dealt with (Brock) Lesnar, Tito (Ortiz), Chuck (Liddell) was f--king king of the world, Ronda Rousey, we've pretty much done deals with everyone on Earth and she is the hardest f--king athlete we have ever dealt with. The problem is she allows herself to be handled by these Hollywood f--king idiots. It's absolutely crazy. We've had all the biggest superstars in the world. You're talking about a girl who hasn't fought in a while. Any time you deal with anyone in f--king Hollywood it's a joke. It's literally a joke, it's comical. You feel like you're in a Saturday Night Live skit. This can't be f--king real. In dealing with her people, I don't know if it can be done."

Seemingly, Carano and the UFC have been negotiating for the several months. Reports suggest that the deal was nearing to a close anticipating Carano to sign the agreement. But recently it appears that a comeback for the 32-year-old is growing more unrealistic.

Carano has not competed in an MMA fight for five years after a loss with Cris "Cyborg" Justino in 2009.
