Other mistake: At the end of the movie where they are looking at the headstone of Jake Hobart, the date on the bottom of the stone is April 3 1913, despite dying shortly before the Titanic sank in 1912.
Other mistake: For someone who has been living on a desert island for at least 10 years, Emmeline seems to have discovered a beauty salon hidden in the paradise. In the close up shots of her hands, she has remarkably nice manicured nails.
Other mistake: At the beginning, when Conrad drives with his friends, one of them takes his head out of the window and says, "I need to Jump". The kid next to him is mouthing his lines.
Other mistake: When Bud is hit by the mechanical bull, he jumps up shouting "You broke my godd**n arm.", and this is a point thought the next 45 minutes or so. The cast he is seen wearing however is only given for a broken thumb, not a broken arm, which is where he was hit.
Other mistake: Someone in the film discusses being "stabbed with a gun".
Other mistake: When Arthur's father takes his ball away (just before Richard Collier signs the register), Richard is looking the other way while Arthur's father puts the ball somewhere behind the counter. Yet, when Richard decides to give Arthur his ball back, he reaches over the counter to the exact place Arthur's father placed it even though Richard never saw where it was placed. (00:54:30 - 00:57:10)
Other mistake: Cpt. Yelland and civilian observer Lasky are trying hard not to mess up with the timeline. Changing little things in the past could have tremendous results in the present/future. However they already disrupted the natural timeline by shooting down 2 Japanese Zeros, killing both pilots, leaving behind CAG Owens in 1941 and rescueing secretary Laurel Scott who would've been killed for sure by the two previously shot down Mitsubishi Zeros.
Other mistake: When Doolittle is running his jeep up the muddy hill near the beginning, the landscape changes. The hill is a straight 40° angle, but in the close shots behind the wheel, it changes to a steep 80° which no vehicle could realistically terrain, except perhaps an army tank. And he stalls out several times and has to back up, which would not happen at the 80* steep. Then he miraculously makes it over the top.
Other mistake: When Tommy tries splashing Rosa during their match she hits the ring mat with her chest and stomach yet seconds later she's somehow knocked out. I never saw her head hit after multiple viewings of that scene.
