Continuity mistake: Why and how would/could Sara dry clean and return Hitch's shirt when, in the process of it being trapped in the cab door, you could see and hear it being ripped to shreds? (00:40:00)
Continuity mistake: Right after Hitch has his bout with food poisoning and he's talking to Sara on the couch, her hair changes. For most of her speech about her sister falling through the ice, the hair on the right side of her face is behind her shoulder. Towards the end of the story it goes in front of her shoulder and then at the end it's back behind it.
Plot hole: When Geoff meets Hitch in the zoo, he says he got his number from Albert Brennaman, but we have not seen a connection between Albert and Vance, so there is no reason for the team to tie it back to Albert and Hitch. Even if the tickets for the club being in Alex's name for Albert and Allegra's date were a clue, then Sara would not have been surprised to see Hitch at the zoo... So how did they know to use Albert's name? Why wouldn't they just use Vance's name, since they actually got the connect from him, believing that it was in fact Hitch's job to hook men up with women? (01:21:30)
Continuity mistake: When Hitch and Albert meet for the first time, the spot of mustard on Albert's cheek changes size from small to large and back down to small.
Continuity mistake: When Sara arrives at the marina to meet Hitch for their breakfast date, it's supposed to be 7:00 AM. However, the sun is bright & almost directly overheard, as shown by the shadows on their faces, illustrating it was really close to mid-day during filming. (00:35:30)
Continuity mistake: Near the end of the movie, Hitch is talking to Sara on the street. If you watch behind her, you will see the same young man in blue satin shorts walk behind her twice. (01:53:10)
Continuity mistake: When Hitch and Sara kiss the first time, Hitch moves his arm up three different times. Most noticeable in the far away shot. (01:11:00)
Continuity mistake: When Hitch is watching Albert for first time, Albert start to clean the spot of mustard in the scene (we can see him from behind) but it is not until the next shot he takes a piece of paper to clean it.
Audio problem: After the article about Hitch is printed, we see him leave is apartment block and get approached by a former client and his now partner. After Hitch says, "See ya later, Tony", we hear Tony's Partner say, "Look Tony," however, her lips do not move.
Revealing mistake: When Hitch is wearing the fat face mask you can see where it has pulled away from his skin right next to his right eye.
Other mistake: In the scene where Hitch first meets Vance Munson, when Vance is pouring the bottle, the liquid pours and stays level at the same time.
Continuity mistake: Near the end after Hitch jumped on the Mini when they are talking; watch behind Sara, the car disappears and reappears several times. (01:45:00)
Continuity mistake: In the scene in Albert's office, immediatly afer he quits his job, his tie keeps swapping from straight to sideways.
Revealing mistake: In the scene where Hitch first meets Albert, Albert spills his soda. The can shoots open and spills over the steps. If you look closely the label on the can is upside down. This would be fine if the coke was spilling out of it but it shoots out and when he picks it back up it is still upside down.
Continuity mistake: During Hitch's flashback at the college while he speaks with the girl on the stairs, the sun changes between shots.
Continuity mistake: During the first time Kevin James and Will Smith meet, Kevin drops a coke and it spills all over the steps in a certain way. However, when Will actually comes over to Kevin, the spill pattern on the steps has changed.
Continuity mistake: When Sara falls off the wave-runner, Hitch jumps in. Right before he falls in, Sara is close to the wave-runner. But when Hitch falls in, Sara is a little further away from the wave-runner.
Plot hole: In the part where Allegra is speaking to Albert in his office doorway and Hitch slips the pen in his pocket, how did he know she looked away? He's behind a solid door.
Suggested correction: He (and we) can hear her rummaging through her purse.
Visible crew/equipment: When Sara meets Hitch for first time at the bar you can see on Sara's glasses the lights of the set.
Other mistake: In the scene at Ellis Island where Sara is looking at the immigration book with Hitch, the security guard looks straight at the camera for a brief moment.
