Here are some photos from the Los Angeles premiere of The Guilt Trip, which stars Seth Rogen and Barbra Streisand. The two actors play son and mother, respectively speaking, who take a cross-country road trip together, and hilarity (presumably) occurs as a result. I kind of adore Seth because he’s a formerly schlhubby guy who’s gotten himself into really good shape over the past few years, and he’s also succeeded outside of (or perhaps in spite of) the Judd Apatow school where he first met stardom in Knocked Up.

Now about these premiere photos. Barbra is an icon (obviously), but that hair screams, “drunk Jennifer Aniston.” So far, there’s been a really huge critical buzz over the chemistry between these two, and it’s been quite awhile since we’ve seen Babs on the big screen, hasn’t it? No matter how you feel about her diva ways, it’s good to have her back. Here are some of Seth’s thoughts on how he related to Barbra onscreen by drawing on his experiences with his own mother. It’s a pretty cute story:

Barbra Streisand picks the films she does carefully, but she had some help when selecting to work on The Guilt Trip with Seth Rogen. See what made these two a perfect mother and son on film

“It was interesting, I was talking to a friend that said to me that, ‘You are an actress, and you should act!’ That was interesting but then I read the script out loud with my son, and he thought I should do it. So I decided, what the hell and do it!” Barbra gushed candidly after a screening of her new film The Guilt Trip at AMC Theaters in Century City on Dec. 2.

But another reason could have been the chemistry she had with her co-star Seth, who was quick to add his thoughts on the similarities between Barbra and his own mother saying, “Barbra met my mother because she came to set, and she went to Barbra’s concert. There are similarities, they are both Jewish ladies, so they have a lot of common ground I would say! They are not that different, my mom was a hippy, my mom is more like her character in Meet the Fockers. My mom was a social worker and talks about sex way too much. she will literally post on her Facebook about Paps smears she has just got!”

Ugh, I will admit that the Pap smear detail is really gross. Maybe Seth was speaking figuratively about that, and his mom merely Facebooks about her cats or the equivalent, but I think his statement is also a very fond one. Obviously, Seth respects his real-life mother, and he spread that affection onscreen to Babs, if the reviews are any indication.

In other Rogen-related news, Seth has also been pinch-hitting for Bill Murray as Peter Venkman in a live reading of the original Ghostbusters script. Jason Reitman (son of the film’s director, Ivan Reitman) says that Seth was the right guy for the reading because “we needed an actor whose rhythms were equally unique to Bill Murray’s and had that kind of a swagger.” Alright, I think Seth is adorable, but he possesses no degree of Murray swagger. Nobody does.
