Best movie of this year hands down!

A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."

Ok... Let's be honest. It cannot be the best movie but is quite enjoyable. The movie has the potential to develop a great plot for future movies

Actress is magnificent and exudes a hypnotic screen presence in this affecting drama.

Two flying aces go to help their friend who is building a dam in New Mexico. It seems his job is being threatened by The Black Ace who wants the dam stopped. The Black Ace and his Mystery Squadron wants the dam stopped because they have discovered a vein of gold that will be submerged when the dam is finished.A good cast (The chemistry between Bob Steel and Big Boy Williams is wonderful) and good action is hampered by poor rear screen work (The rear screen footage doesn't match what is happening in front of it) and poor model work (you can almost see the wires). This isn't to say its a bad serial, its not, its just that the budget limitations make the film feel creakier then it is. Worth a look.

I remember this movie serial as a boy in the thirties,we would ask our mother's for a penny on a Wednesday after school,and line up at the local movie house along with hundreds of kids..mostly boys,it always promised fast action,the Mystery Squadron who had their hideout in a mountain cave,the Black Ace the leader always seemed as though he would never would be revealed,would provide the bad deeds,as the action heated up thousands of young feet would stomp on the balcony floor,it was a wonder that it never collapsed.it would build to a crescendo,THEN it would stop suddenly,everyone would hold their breath as the hero would be put in seemingly inescapable peril,NEXT WEEK...see the next thrilling chapter,we would pile outside still gripped in the spell and discus with actions what had taken place,we would then speculate as to how he was going to get out of this latest fix,Bob Steele,Tom Mix,Hoot Gibson,Buck Jones,Ken Maynard,our heroes,who never kissed a girl,in our games no one wanted to play the Black Ace.Happy innocent days.

Like all Mascot serials, "Mystery Squadron," was made on a slight budget. But this didn't keep it from being a fun watch. The serial was loaded with good stunt action, and those of you with a bit of interest in vintage airplanes,(circa 1920's) plenty of good aerial action, and fine stunt flying. Of course, in most Mascot serials there was a masked villain, The Black Ace, who's identity would only be revealed in the finial chapter. If you enjoy movie serials, give it a try. One of the best Mascot serials.

This film falls toward the middle of Mascot's serial output. It isn't as exciting as some (The Hurricane Express), as entertainingly ludicrous as others (The Whispering Shadow), as lavish as a few (The Phantom Empire) managed to be. The actors' performances are all on par with their respective usual standards, and stick fairly close to typecasting. The Tavern Hotel, where much of the action is set, is an illogical conceit: a large building seemingly in the middle of nowhere, housing no more than five people all of whom are familiar with the secret passages which honeycomb the walls. Of course, in Mascot serials logic is pretty much beside the point, and that's okay.
