"The Mentalist" season 7 spoilers revealed that production has started as cast Tim Kang provided a sneak peek into the filming process on his social media. The series premiere date, however, is still unknown.

On July 30, Tim Kang posted two photos at 7:49 a.m. on what appeared to be an office, while the cast and crew prepare to shoot scene. He captioned the first photo, "day one of season 7." Moments later, he uploaded another photo on the same location shoot along with the caption, "Had to be here at 5am. I'm sleepy. HA!"

According to Cartermatt, filming has started this past week and will likely continue up until the end of the year. Because of the shortened season, however, "The Mentalist" season 7 casts Simon Baker and Robin Tunner along with the rest of the crew will have a longer break.

"The Mentalist" season 7 spoilers revealed the struggles that Patrick Jane will encounter when a new character is introduced in the show. The series is expected to be more "action-packed" because of fewer episodes.

The TVGuide reported "The Mentalist" season 7 spoilers when it said that the character of Michelle Vega will appear in future episodes and her "by-the-book" orientation will clash with the unorthodox methods of Patrick Jane (Simon Baker).

Michelle Vega is also very ambitious and is hinted to be very qualified for the position.

As Michael Ausiello earlier wrote "The Mentatlist" season 7 spoilers at TVLine: "A new woman is about to enter Patrick Jane's (professional) life. The CBS drama is casting the series regular role of Michelle Vega, a rookie FBI agent who is a student of combat and weaponry and is unfazed by high-pressure situations."

The CBS still hasn't provided the airing schedule for the seventh season of "The Mentalist," although it's reported that there are only 13 episodes for what could be the final season for the series.
