Castle (2009)

After Hours - S5-E8

Plot hole: Beckett and Castle lose their cell phones and wallets and are being chased by the mob. Beckett steals a cell phone from a car but can't use it, since it is locked and then shut off remotely. Any cell phone can always dial 911, whether locked or blocked from service.

For Better or Worse - S6-E23

Continuity mistake: At the end of the episode, the Mercedes S class that is burning is not the same car that Castle drove previously in the episode, it's an older model one. Either it's a mistake or has to do something with the plot resolution, decide yourselves...

Sucker Punch - S2-E13

Continuity mistake: When the Captain hands Beckett his flask, from behind she unscrews the cap and lifts it to her mouth. We then cut to a front-on shot of Beckett and she lifts it to her mouth a second time.

Overkill - S2-E23

Audio problem: When Demming writes "Stolen books" on the white board and says, "Killed for a fortune in stolen books, so I'll run the work crews and see if anybody has priors", his lips don't match what he's saying at all.

Home Is Where the Heart Stops - S1-E7

Visible crew/equipment: When Castle and Beckett step into the elevator whilst talking about The New York Review of Books, a cameraman is reflected in the left door of the elevator as it closes and the scene ends.

Limelight - S6-E13

Revealing mistake: When Beckett shows Castle the newspaper article about his "lunch date" with his ex-wife Gina, the text in the article repeats itself.

The Lives of Others - S5-E19

Continuity mistake: When Beckett and Castle kiss at his party at the end of the episode, the camera is behind Castle, and Beckett's head is leaning toward her left shoulder. When the shot switches to behind Beckett, her head is leaning to the right. Then it switches back to left.

Reality Star Struck - S5-E14

Continuity mistake: When they first arrest Penelope they show her first fingernail broken. In the next scene when she's talking about the nail, she shows her middle fingernail broken.

Headhunters - S4-E21

Continuity mistake: During Shea's interrogation scene, he has blood running from his head down to his eyebrow which collects into a blob. Between shots, this blob of blood disappears and reappears.

Under Fire - S6-E11

Other mistake: At some point during filming, Stana Katic injured her right hand. At episode's end, when Beckett hugs Esposito and Ryan after they're rescued, her index and middle fingers are taped together, and the injury doesn't appear in any other scene.

Murder He Wrote - S5-E4

Revealing mistake: After Castle and Beckett are arrested for interfering in Chief Brady's investigation, a deputy tells them that Brady wants to speak to them; Beckett stands up to leave the holding cell, but is held back by the pair of handcuffs chaining her to the bench. The cuff is not actually on Stana Katic's wrist; she's just holding it in her hand.

Murder He Wrote - S5-E4

Factual error: On the way to the Hamptons, Castle's car is driving on the left side of the road, even though they're in the US (where people drive on the right side of the road).

Flowers for Your Grave - S1-E1

Other mistake: Beckett and Co are in the mental patient's apartment. She opens one of Castle's novels. The title page says that it's called "A Skull at Springtime." However, on the opposite page, it says that the book is "Storm Fall."

Secret's Safe with Me - S5-E3

Continuity mistake: Castle and Beckett are talking about the case in the precinct and his coffee runs out. Beckett offers to go refill the mug. She grabs his white mug in her right hand. In the next shot, it is now in her left hand. A blue mug is in her right hand instead.

Always - S4-E23

Continuity mistake: Near the end of the episode, when Beckett shows up at the loft and kisses Castle, her left hand constantly jumps from his cheek to his shoulder.

Last Call - S3-E10

Continuity mistake: When Castle and Beckett go to question Jeffrey McGuigan, Beckett raises her badge twice: once while the camera is on Guy Wilson, and a second time when the shot cuts and the camera is on Stana Katic.

Number One Fan - S6-E4

Character mistake: When Beckett is bemoaning losing her job with the government, she says she hasn't been out of work since she was fifteen. But in "Always" at the end of season four, she is suspended by Captain Gates and chooses instead to resign from the force.

Driven - S7-E1

Continuity mistake: When Beckett, Esposito and Ryan interview the fruit stand vendor, he states that he saw a bronze Mercedes drive by, to which Esposito replies, "That's Castle's car." In the previous scene at the car crash site, Ryan asks Esposito to check the back corner of the car for damage, which is silver or gray, not bronze, in color.

I, Witness - S7-E13

Continuity mistake: When Castle and Beckett are in bed, their pillow cases are dark and patterned. When Beckett wakes up to find Castle gone, the pillow cases are white.

I, Witness - S7-E13

Revealing mistake: When Castle answers his phone at the start of the episode, his phone is on the lock screen instead of in call mode.
