Joss Whedon, director of upcoming "Avengers 2: Age of Ultron" film, confirmed on Twitter that things are going according to plan for Marvel's much anticipated movie sequel. The film director revealed on his Twitter account @josswhedon that the production team is already halfway through shooting.

On Saturday, May 31, Joss Whedon made the post on Twitter with an image attached perhaps to describe the "Avengers 2" filming experience. The director shared that he thinks he is holding up better than usual with the hashtag #yoga in the end. Click HERE to see photo.

The Movie Pilot report speculates that the fast track filming on the "Avengers 2: Age of Ultron" is meant for an earlier release date instead of the anticipated May 2015 schedule. Aside from director Joss Whedon, "Avengers 2" cast member Mark Ruffalo also teased the fans via Twitter about something they should look forward to in the upcoming film.

The 46-year-old actor revealed on his Twitter account @MarkRuffalo that his character, Hulk, will have another excellent scene in the film which is equally delightful to the part in "Avengers" when the green giant slammed Loki (Tom Hiddleston) several times. The actor did not further reveal any information on that scene.

"Let me put it to you this way. There is a Hulk surprise that is equally delightful as when he smashed the bejesus out of Loki [in Avengers]," Ruffalo posted. According to the Enstars report, Mark Ruffalo admitted that he would want to work on a standalone "Hulk" film soon.

However, there are no details yet from the movie producers if the project will push through or not. Actor Mark Ruffalo confessed on his Tumblr post the he really likes for the Hulk movie to happen one day but the timing has to be just right.
