Peter Lorre credited as playing...
Mr. Moto
- Kentaro Moto: The art of professional wrestling consists of two parts groan, two parts acting, and but one little part of skill.
- Twister McGurk: [amazed by Moto's martial arts abilities] If you was a pro, I could never get to be world champion.
- Kentaro Moto: You may depend on me retaining my amateur status.
- Twister McGurk: Hey, Mr. Moto! Indemnify me for these mugs!
- Kentaro Moto: Please release him, Colonel. He is my assistant... self-appointed.
- Kentaro Moto: You've been a great help, and I want to thank you.
- Twister McGurk: I wanna thank you too, pal. That hold yuh showed me I'm gonna keep in my wretlin' "prepatory."
- Kentaro Moto: [noticing the intercom is switched on] Is this a private conversation or are we broadcasting?
- Twister McGurk: [in awe of judo techniques] Hey, I've seen everything, but a little shrimp like you throwing The Sailor gets me!
- Kentaro Moto: What I've used is simple, but it has served me well on many occasions.
- Capt. Dahlen: [as Moto lays in pain on a gurney] Well, Mr. Moto, you picked a bad time to get afflicted.
- Kentaro Moto: [Marr sadistically presses his foot on Moto's appendix] Unfortunately we cannot select a time for our afflictions.
- Kentaro Moto: [to Twister] You can obtain the confidence of criminals when one is branded a criminal.
- Joan Castle: Mr. Moto!
- Kentaro Moto: Good evening, everybody.
- Joan Castle: He's a detective. He's come here to arrest my father. You can't take him! He was framed! Please you promise me to protect us until dad's prove innocent.
- Kentaro Moto: Don't be so alarmed. Moto was only an impersonation. Very convenient for the moment.
- Joan Castle: I - I don't understand.
- Grant: Just a penny-ante gangster playin' detective.
- [Joan looked up the newspaper of San Juan Tribune, "Governor Slain by Bogus Mr. Moto! Notorious Killer Shimura and Accomplice Make Sensational Escape". They broke out of jail and resisting arrest]
- Joan Castle: Shimura. You murdered the Governor. It was you, you framed my father. Now we can go back to San Juan. This proves dad innocent.
- Grant: Sure, sure. Now you go back to your cabin and looked after that fever. I'll take care of this.
- Joan Castle: But we can't waste anytime.
- Grant: Bill, take her back to her cabin.
