Question: Turtles All the Way Down is the first published work by John Green since what book whose title comes from "Julius Caesar"?
Context: The World in Six Songs: How the Musical Brain Created Human Nature is a popular science book written by the McGill University neuroscientist Daniel J. Levitin, and first published by Dutton Penguin in the U.S. and Canada in 2008, and updated and released in paperback by Plume in 2009, and translated into six languages.  Levitin’s second "New York Times" bestseller, following the publication of "This Is Your Brain on Music", received praise from a wide variety of readers including Sir George Martin, Sting, Elizabeth Gilbert, and Adam Gopnik.  The "Los Angeles Times" called it "masterful".  The "New York Times" wrote: "A lively, ambitious new book whose combined elements can induce feelings of enlightenment and euphoria.  Will leave you awestruck." " The Times" wrote "Levitin is such an enthusiastic anthropologist, such an exuberant song and dance man, such a natural-born associative thinker, that you gotta love the guy."  It was named one of the best books of 2008 by the "Boston Herald" and by "Seed Magazine". "She's So Modern" is a song by The Boomtown Rats.  It was the first single taken from the band's second album "A Tonic for the Troops", whose title comes from a line in this song: "Charlie ain't no Nazi, she just likes to wear her leather boots, 'cos it's exciting for the veterans and it's a tonic for the troops".  The single continued the Rats' high-energy post-punk/new wave sound that had typified earlier releases, but its fame would later be eclipsed by that of the band's more ballad-like global hit "I Don't Like Mondays".  It has been described as "harmlessly smirking bubblegum "a la" The Knack". A random number book is a book whose main content is a large number of random numbers or random digits.  Such books were used in early cryptography and experimental design, and were published by the Rand Corporation and others.  The Rand corporation book "A Million Random Digits with 100,000 Normal Deviates" was first published in 1955 and was reissued in 2001. Nemesis at Potsdam is a 1977 book whose title is drawn from Greek mythology; Nemesis is the Greek goddess of revenge.  The implication is that at the Potsdam Conference (17 July to 2 August 1945) the victorious Allies of World War II took revenge on the Germans, entailing significant territorial losses in Eastern Europe and the forced transfer of some 15 million Germans from their homelands in East Prussia, Pomerania, Silesia, East Brandenburg, Czechoslovakia, Hungary, and Yugoslavia. Gaius Crastinus (c. 85 BC – 48 BC) was a soldier in Julius Caesar's 10th legion during his Gallic Wars.  He had first joined either the 8th or 9th legion in 65 BC, when Pompey Magnus had first raised these two legions in Spain.  He transferred over to the 10th legion as a junior-grade centurion in 61 BC when it was first formed, after being handpicked by Caesar.  After joining the 10th legion, he commanded a Century.  Crastinus fought throughout Caesar's Gallic campaigns, and was present at the Battle of Alesia, where he witnessed the surrender of the Gallic chieftain Vercingetorix to the forces of the Roman Republic.  Early in the war, Crastinus commanded his unit as it repelled an attempted crossing of a river by the Helvetii.  Crastinus, whom Caesar considered to be amongst his best soldiers, was promoted by Caesar to the rank of Primus Pilus, or "First File" Centurion.  This rank was one of exceptional prestige, since centurions of this rank commanded the first ("primus"), and most important, century in a Legion.  With this rank, Crastinus also would have outranked all other centurions in his legion, as it was the highest possible rank of any enlisted Roman soldier. Gaius Valerius Troucillus or Procillus ("fl. " mid-1st century BC) was a Helvian Celt who served as an interpreter and envoy for Julius Caesar in the first year of the Gallic Wars.  Troucillus was a second-generation Roman citizen, and is one of the few ethnic Celts who can be identified both as a citizen and by affiliation with a Celtic polity.  His father, Caburus, and a brother are named in Book 7 of Caesar's "Bellum Gallicum" as defenders of Helvian territory against a force sent by Vercingetorix in 52 BC.  Troucillus plays a role in two episodes from the first book of Caesar's war commentaries (58 BC), as an interpreter for the druid Diviciacus and as an envoy to the Suebian king Ariovistus, who accuses him of spying and has him thrown in chains. The Fault in Our Stars is the sixth novel by author John Green, published in January 2012.  The title is inspired by Act 1, Scene 2 of Shakespeare's play "Julius Caesar", in which the nobleman Cassius says to Brutus: "The fault, dear Brutus, is not in our stars, / But in ourselves, that we are underlings."  The story is narrated by Hazel Grace Lancaster, a 16-year-old girl with cancer.  Hazel is forced by her parents to attend a support group where she subsequently meets and falls in love with 17-year-old Augustus Waters, an ex-basketball player and amputee.  A feature film adaptation of the novel directed by Josh Boone and starring Shailene Woodley, Ansel Elgort and Nat Wolff was released on June 6, 2014.  Both the book and its film adaptation were met with strong critical and commercial success. Julius Caesar is a 1950 film adaptation of the Shakespeare play "Julius Caesar".

Bradley himself played Brutus, and Harold Tasker had the title role.  Bradley recruited drama students from his alma mater Northwestern University for bit parts and extras, one of whom was future star Jeffrey Hunter, who studied alongside Heston at Northwestern.
