Robert De Niro

Have you ever rewatched The Hangover and thought, man, these guys are just too fresh-faced and inexperienced to properly party? In the off chance that has ever happened, you're in luck with the trailer for Last Vegas, in which aging stars Michael Douglas, Morgan Freeman, Kevin Kline, and Robert De Niro star as four friends who head to Sin City for one of their bachelor parties. Once there, they are ready to "party like it's 1959," and the Lipitor jokes start flowing like wine.

All told, the preview is pretty cute, mostly because the actors are so beloved and really seem to be having a good time. If anything, it's worth it to watch Freeman discover vodka Red Bull cocktails and the obvious post-vodka Red Bull dancing. Last Vegas comes out Nov. 1, and you can watch the trailer after the jump.

If you're a romantic-comedy lover with a soft spot for wedding movies, then trust me — you've already seen The Big Wedding. The premise itself probably sounds familiar: when a family comes together for a wedding, hijinks ensue, people don't get along, and secrets are revealed. Even most of the cast members have played similar roles before. Diane Keaton and Robert De Niro play the groom's parents, Katherine Heigl is the bitter sister, and Amanda Seyfried plays the bride. And the unoriginality doesn't stop there! If you're tempted to watch The Big Wedding, then let me advise you that you can get the same fix by watching the movies below. Their accomplishment: they each tackled elements of The Big Wedding first — but better.

1. It's Complicated: In Nancy Meyers's comedy It's Complicated, the romance between the divorced couple played by Meryl Streep and Alec Baldwin feels organic and realistic. That's not the case for Keaton and De Niro's characters in Ellie and Don, the divorced parents of groom Alejandro (Ben Barnes) in The Big Wedding. Oh, it is complicated for them — despite the fact that they haven't been married for over 10 years, sparks still fly between them during the wedding weekend — even though he's already moved on with someone else. When Ellie and Don move closer to a reconnection, it's icky and doesn't make sense for their characters.
2. Wedding Crashers: The Big Wedding is rated R, so there's a healthy dose of raunchy humor, but there's nothing you haven't seen before, especially if you've seen Wedding Crashers. There is even one scene that is straight out of the Owen Wilson and Vince Vaughn classic. For frisky family members and R-rated wedding jokes, just watch Wedding Crashers.

Get the rest of the list after the jump.

Already a megastar in the world of Internet cats, Lil Bub is now a Hollywood A-lister too. At the Tribeca Film Festival to debut her documentary, Lil Bub & Friendz, which is about its famous title character and her contemporaries, like Nyan Cat, Grumpy Cat, and Keyboard Cat, Lil Bub attended the directors brunch on April 23 and rubbed elbows with the one and only Robert De Niro. The legendary actor was so happy to meet Lil Bub — who is a legend in her own right — he scooped the "perma-kitten" up in his arms and proudly posed with her.

Below is a poster for the feline documentary.

Several of Silver Linings Playbook's stars have been nominated for their work at this year's Oscars, and they each made time to stop by today's Oscars Luncheon press room to chat. Best supporting actor nominee Robert De Niro talked about why he wanted to work with director David O. Russell so much and whether he, as a veteran actor, gives advice to his colleagues.

On the fun of working on Silver Linings Playbook: "David [O. Russell] is terrific, and I wanted to work with him for a while. This came along — we had other projects that maybe happened but then didn't. So this one, as soon as he wanted to do it, I said, 'I'm in.' He did a rewrite, and I didn't care what the rewrite was. I knew whatever he did would be good, just based on what I've seen. It was that simple."

On working with his Silver Linings costars: "The actors were great. I like to work with everybody, and young actors, of course. If they ever ask me for advice — I never volunteer it — but if they ask me, I'm always very happy to give it."

On whether another Oscar nomination is still exciting: "It's still a big deal. Yeah."
