As ruler of your 10th H, Venus would be a strong significator of your career goals and ambitions; Venus in Leo favors the entertainment and social fields especially relating to comedy, drama, romance and children. You would have to overcome your natal Venus/Mars challenge though, in order to maintain good relationships with others.
Since Venus also rules your 3rd H, writing, communications and public speaking could also be supported. Taurus can be creative in terms of design and decoration; Mars/Gemini, writing and media work. It is good to have the adaptability and versatility of this Mars, but as you have noted you need to develop consistency and follow through. The film industry typically falls under the influence of Pisces, where we find Neptune supporting Jupiter, another indicator of creativity.
Indeed your options are many, and much depends on how you interact with others who can assist and support you. You have an abundance of fire [inspiration,inventiveness] and earth [practical, reliable and responsible] energies to fuel your ambitions, yet you also lack in the energies of Air [the mind, socialization] and water [emotional connections] and these can be areas that serve to trip you up.In the end, the ultimate question comes down to 'what do you want to do?'
