The tip of the iceberg: the small perceptible part of a much larger situation or problem that remains hidden.

Corporate life is horrible; Dilbert proved that in cartoon form and Keanu Reeves lived it in the computer simulation of the terror that is cubicle living. The nine to five grind can cause mannerisms that are beyond that of a grounded individual and it's that mindset that Spanish director David Cánovas explores in his latest film.

The Tip of the Iceberg digs deep into the dehumanised world of corporate work culture through its cinematic telling of the Antonio Tabares play, which is based on the true events of a real life case (in 2009, 20 employees of a French national telephone company committed suicide). Cánovas stitches his narrative with multiple threads: corporate espionage, personal problems within the company, and even vending machine woes all make up this incredible cinematic sweater. Like the title hints at, there's so much more boiling just underneath the surface of this tense drama. What the film successfully achieves--and this can't be said for a lot of movies based in a hectic environment--is a feeling of incredible stress and urgency.

Phones constantly buzzing on a table during a meeting, conversations taking no longer than necessary, and the inadequacies of a vending machine that refuses to work all add to the frantic nature of Cánovas' workplace. There's also no reliance on quick cuts to build this atmosphere. Instead, Cánovas creates almost painfully long takes and frames everything with a starkness that resembles the tall, structural office buildings--the tombs these worker bees are "trapped" in.

The frantic nature also starts to rub off on the lead actress of the piece, played brilliantly by Maribel Verdu. Tasked with "being a detective but not, because you're an analyst," Verdu evolves her character with extreme precision over the film's duration. Starting off fiery and full of self-confidence, the tension eventually gets to her, until at one point she starts to succumb to being part of the larger machine.

The Tip of the Iceberg is Cánovas' debut film and it is surely only the start of the impressive work we can expect to see from this talented director. Go watch The Tip of the Iceberg in cinemas and get lost in the story. It might remind you a little of your own workplace (we all have broken vending machines, don't we) but if it feels just as stressful, maybe turn off Slack and finally use up those vacation days. [And on a more serious note: if you do feel like the work pressure is too hard and have suicidal thoughts, please talk to someone.]
