Veep season 7 isn't holding back with its celebrity cameos. Previous seasons have seen everyone from Academy Award winner Allison Janney to Parks and Recreation's Adam Scott making guest appearances, and the final season includes a wide variety familiar faces.

After facing her fair share of failures, Selina Meyer is running one final campaign to the White House in Veep season 7. Getting the old gang back together, Selina is confronting old enemies, losing close supporters, and forming new alliances on her second attempt at the presidency. With a team including Tony Hale, Anna Chlumsky, Reid Scott, Sam Richardson, Kevin Dunn, and Gary Cole, Veep's final season is en route to sending the series off in familiarly heightened fashion with familiarly heightened characters. And, like previous seasons, there are plenty of celebrity cameos in Veep to add a few doses of star power.

As per usual, the Veep season 7 celebrity cameos are either there to help or hurt Selina's campaign. And, though one of these cameos is basically a blink-and-you'll-miss-it appearance, others actually play a significant role in assuring Selina has a legitimate shot at ending the series as President of the United States of America.

William Fichtner - One of the most prominent celebrity cameos in Veep's season 7 is William Fichtner as mega-donor Felix Wade. Though he's given very little setup, his cockiness and influence speaks for itself, ultimately bringing out the true colors of Selina Meyer and Tom James (Hugh Laurie), who are both running for President. Outside of television, one of Fichtner's most recognizable cameos was in The Dark Knight when he faced off against Heath Ledger's Joker in the opening scene.

Keegan-Michael Key - Of Key & Peele fame, alongside Academy Award-winning screenwriter Jordan Peele, Keegan-Michael Key has a small, but significant role to play in Veep's final season. As Selina attempts to win over voters, she crosses paths with Key's Jordan Thomas Jr., a reverend in South Carolina who might be inclined to support Selina were it not for US Senator Kemi Talbot (Toks Olagundoye) also in the race. Whether or not he has a change of heart in the final few episodes of Veep season 7 remains to be seen.

Andy Daly - Perhaps best known for the Comedy Central series Review, which he hosted, and voice work on a number of animated shows, like Bob's Burgers and Adventure Time, Andy Daly makes his debut in Veep season 7 in a small role that holds a great deal of weight - or should, at least. Though he's (accidentally) brought on as Selina's campaign manager Keith Quinn, he plays a mostly background role, seeing as Selina can't replace him so late in the game.

Rhea Seehorn - Jumping from Better Call Saul to Veep, Rhea Seehorn plays Michelle York in the show's final season. Not only is her character Tom Jones' new chief of staff, she's also hiding a fairly significant secret that helps Selina navigate through her competition's various weak spots. She's also a verbal punching bag for Selina, reminding everyone (audiences and characters alike) how relentless Selina can be when the going gets tough. Seehorn also had a small role in Jordan Peele's Twilight Zone reboot.

Michael McKean - Another Better Call Saul alum joining Veep in season 7 is Michael McKean. A veteran actor best known for his roles in everything from Clue (he played Mr. Green) to most of Christopher Guest's mockumentaries (Best in Show, A Mighty Wind), McKean is playing the Governor of Iowa in an episode. Incidentally, both McKean and Seehorn worked with Veep creator Armando Iannucci on the first failed attempt at adapting The Thick of It (which Veep is based on) as an American series for ABC in 2007.

Dan Mintz - The briefest cameo in Veep's final season belongs to Dan Mintz. Best known as the voice of Tina Belcher on Bob's Burgers, Mintz has a throwaway cameo in Veep as a vendor at a state fair. However, he's given the opportunity to deliver a disposable line that temporarily breaks from the action of the episode's story. The focus on the line appears to only be included for fans who will undoubtedly recognize his distinct voice.
